Broadcom Overtakes Qualcomm as Largest IC Design House in 2Q20

According to the revenue ranking of top ten IC design companies for 2Q20 compiled by TrendForce, Broadcom was able to capture number one position by surpassing Qualcomm in quarterly revenue. Despite strong demand for 5G products driven by WFH and distance education needs, Qualcomm’s upward momentum in 2Q20 was constrained due to the delayed release of Apple’s latest iPhones.

TrendForce analyst C.Y. Yao indicates that new product releases by Apple during third quarters had typically contributed to Qualcomm’s second quarter revenues in the past. Delayed iPhone releases this year, however, led to a slowdown in Qualcomm’s chip revenue growth. Qualcomm registered a modest 6.7% revenue growth YoY in 2Q20. On the other hand, although Broadcom retook first place in terms of quarterly revenue, escalating tensions between China and the U.S. had a negative effect on its semiconductor revenue performance, which declined by 6.8% YoY in 2Q20.

Nvidia now includes revenue from Mellanox as part of its data center revenue after the former acquired the latter earlier this year. The addition of Mellanox was able to compensate for Nvidia’s shortfall in professional visualization and automotive revenue. On the whole, Nvidia posted excellent revenue performance for 2Q20 and increased its revenue by 47.1% YoY, the highest percentage growth in the top 10 list. AMD scored the second highest YoY percentage growth in 2Q20, at 26.2%, behind Nvidia, due to the outstanding receptions of its Ryzen and EPYC processors in the notebook and server markets, respectively.

Xilinx has traditionally counted the wired and wireless network equipment market as one of its main revenue drivers. However, the department responsible for those markets posted a 33.2% YoY decrease in quarterly revenue, and the COVID-19 pandemic took a heavy toll on the global automotive market, leading to a decline in Xilinx’s automotive revenue. For the first time ever, Xilinx registered a double-digit YoY quarterly decline. Likewise, Dialog saw decreased revenue from its custom mixed-signal IC, leading to a YoY decrease of 10.1% in overall 2Q20 revenue.

In the face of escalating sanctions by the U.S. Department of Commerce, Huawei subsidiary HiSilicon is unlikely to fulfill chip demand from Huawei’s various product lines. Since U.S.-China tensions are yet to improve, HiSilicon’s new Kirin processors to be released in 2H20 is expected to be the final mobile processor released by the company. Much like the Kirin, other chips from Huawei, including server CPUs, AI chips, and 5G chips, may face a similar fate.

Taiwanese IC design companies MediaTek and Realtek maintained their excellent performances during the quarter, reaching YoY revenue growths of 14.2% and 18.8%, respectively. In particular, MediaTek was able to successfully deploy its products to the 5G mid-range smartphone market with its 7nm process technology and cost optimization measures, in turn raising its revenue and gross margins.

C.Y. Yao believes that, on the whole, the outlook for the global IC design revenue in 2020 is relatively positive because of strong demand in 3Q20 for WFH- and distance education-related products, in addition to component demand from the data center, 5G infrastructure, and 5G smartphone markets.

Marvell Joins TSMC’s Upper Echelon Customers of 5nm Chips

Marvell, after reinventing itself as a supplier of data infrastructure silicon, has joined the upper echelon of Taiwan Semiconductor Manufacturing Co. (TSMC) customers by winning capacity allocation at the 5nm node.

Marvell and TSMC said they will deliver a comprehensive silicon portfolio using the world’s most advanced process technology, which is now entering production. The partners are aiming for the more-than-Moore era with die shrinks to 5nm from 7nm and packaging innovations that boost the density of storage, bandwidth, speed and machine-learning capabilities while cutting power consumption.

Marvell updated its logo earlier this year.

“We’ve been able to achieve on average 40 percent lower power for a given design point and performance point,” Marvell ASIC Unit general manager Kevin O’Buckley said in an interview with EE Times. “We’ve been able to achieve 40 percent greater integration, mostly measured as die area shrink, which can be used either to pack in more performance in a given die area or in some cases, lower costs.”

One of the fastest growing parts of the infrastructure semiconductor market is in switching and custom-built accelerator products as cloud-data hyperscaler companies like Microsoft and Google aim to move workloads that are running on general-purpose compute devices like CPUs and GPUs into custom silicon “because they own the whole stack from software all the way to the transistors,” O’Buckley said.

With multiple designs under contract for its 5nm portfolio, Marvell is developing solutions across a range of markets with first products sampling by the end of next year.

Marvell sees growth potential in 5G despite losing the Huawei business more than a year ago when the US government blacklisted the Chinese company. Marvell counts Nokia, Ericsson and Samsung among its 5G infrastructure customers.

TSMC needs big-league customers to fill a gap left by Huawei’s HiSilicon chip-design unit, which earlier

this year accounted for about 14 percent of sales revenue at the world’s biggest semiconductor foundry. HiSilicon used TSMC’s 7nm process technology to make its Kirin processors.

TSMC’s largest customers currently include Apple, AMD, MediaTek and Qualcomm.

Core businesses

Marvell sees three areas — 5G infrastructure, enterprise networking, and cloud data centers — as its core businesses. In the future, Marvell expects automobiles to be another growth driver.

O’Buckley used Marvell’s Octeon product line as an example of how TSMC’s 5nm node can help create new applications for embedded infrastructure in a range of wired and wireless networking equipment including switches, routers, secure gateways, firewalls and network monitoring solutions.

“In advanced technology, the capability of our Octeon platforms moves to higher performance capability while preserving the key power envelope for things fitting on a PCI card,” O’Buckley said. “We’ve been able to push that application viability to things like 5G carriers where they have much more aggressive power-envelope requirements and frankly more stringent cost targets than some enterprise applications.”

Marvell says Octeon is the world’s most widely deployed data processing unit (DPU) for data-center scale computing that enables acceleration and offload capabilities, including Smart NICs and security accelerators.

Machine learning

Marvell says machine learning accelerators are another example of why it’s critical to migrate to 5nm from 7nm.

“A lot of folks building a world-class machine learning accelerator would not even be able to fit all the content in the reticle with a 7nm design,” Marvell Integrated Systems Technical Director Mark Kuemerle told EE Times.

Block diagram of Marvell’s Octeon.

The company is working with TSMC on chiplets designed for low power consumption with efficient interconnect between different die. Marvell is creating scalable systems for machine learning accelerators and data centers by to moving to 5nm, he said.

“The barrier to entry for a lot of high-end switching applications is being able to fit all the content onto a single reticle,” Kuemerle said. “Interface chiplets are a critical part of the strategy to scaling content. We can use these die-to-die interconnect topologies to build a scalable system so a customer doesn’t need to make multiple products to fit each part of their market.”

Growing ASIC business

Marvell expects more of its sales to come from ASIC design.

Customers can contribute to the design, Marvell CEO Matt Murphy said in a May 2 conference call with analysts. “We stitch it together. We can do it very quickly without the customer having to hire a gigantic design team and take three years.”

If customers have a vision for a product and an implementation that’s not perfectly aligned with Marvell’s standard products, the company will develop ASICs for system integration into a single module, according to O’Buckley. Customers may also want to modify Marvell’s standard products through customization with their IP as an alternative to a full-custom ASIC build, he said.

“A very real portion of our revenue portfolio today comes from customized products. I would say north of single digits,” O’Buckley said. “However, the directional profile is for increasing that share over time.”

A major driver of that is hyperscaler customers that have the ability to make investments in products that support their implementation needs, he said.

Behind Marvell’s 5nm solution set is the company’s IP portfolio that covers infrastructure requirements including high-speed SerDes up to 112Gbps long-reach processor subsystems, encryption engines, system-on-chip fabrics, chip-to-chip interconnects and a variety of physical layer interfaces. These technologies are in development on TSMC’s 5nm process.

Foundry partners

Marvell’s recent acquisitions include foundry partnerships with companies such as Samsung and GlobalFoundries. Marvell expects those partnerships to shrink in the future.

“We are buying wafers at some legacy nodes like 14nm and 28nm from foundry companies that simply are not making the investment in 7nm and beyond,” O’Buckley said. A consolidation at the advanced nodes will concentrate those partnerships away from what was a more diverse group, he said.

TSMC endorsed its alliance with Marvell.

“We are proud to partner with Marvell to serve the data infrastructure market with cutting-edge silicon and are committed to supporting their growing needs in development, quality, supply and capacity,” Kevin Zhang, senior vice president of business development at TSMC, said in a press statement. “In the 5G era, more applications than ever are demanding the most advanced silicon technology we can provide. We look forward to collaborating with Marvell to meet these demands with our combined design and process expertise and extend our long history of partnership to the 5nm generation and beyond.”

Marvell teams are working with TSMC on development at the 3nm node to ensure that the company is positioned to develop products in the next few years, O’Buckley said.

NASA Prototypes X-57 All-Electric Airplane

We’ve reported extensively on the rapidly maturing and scaling of electric vehicles. Researchers are also looking at other modes of transportation that could be powered by electric motors, up to and including all-electric airplanes.

While NASA (the first “A” in the space agency’s acronym stands for “Aeronautics”) is devoting valuable supercomputing resources to model and simulate a new prototype, commercial aviation experts note that all-electric aircraft still have a long way to taxi when it comes to technical considerations like battery energy density.

X-57 electric motor (Source: NASA)

For their part, NASA researchers said development of the X-57 “Maxwell” all-electric aircraft focuses on new battery technologies and the prospect of using less fuel while reducing aircraft emissions. “NASA researchers are looking at ways to improve aircraft, not reinvent them,” program officials note.

NASA Ames Research Center in Mountain View, Calif., is leading modeling and simulation efforts using the space agency’s Pleiades supercomputer. Simulations are creating accurate computer models of aerodynamic performance. Those models will then be incorporated into the X-57 flight simulator, a key tool for aviation research.

Computer modeling will be followed by scale models, wind tunnel tests and prototype flight tests. Test flights will use a modified Tecnam P2006T aircraft, eventually ramping up to test wingtip motors and fabrication of a new wing.

While battery energy density remains a big hurdle to development, NASA researchers note that electric motors can be installed just about anywhere on aircraft to improve efficiency. One version of the X-57 prototype includes 14 battery-powered motors and propellers. A dozen would be used for takeoffs and landings while two wingtip engines would provide propulsion and stability during level flight.

Those motor can’t compete with the horsepower of combustion engines, but they are smaller and lighter.

The current battery configuration includes commercial lithium-ion cells packaged as a pair of 400-pound cells placed in custom-designed battery packs stowed in the cabin. That power plant would supply 23 kilowatt hours of energy, according to NASA’s X-57 Maxwell web site.

X-57 battery pack
(Source: NASA)

Some suspect all-electric airplanes remain, well, pie in the sky. “I love the idea of an electric motor instead of an internal combustion engine,” said veteran pilot and software engineer Gregory Travis. “But I don’t see how they are going to get battery energy density high enough to meaningfully compete with hydrocarbon fuels.”

Instead, a renewable energy approach to aviation should focus on fuel cell approaches, Travis added, not unlike the power supplies that enabled Apollo astronauts to fly to and from the moon. “What we need is a fuel cell that can directly convert liquid hydrocarbons into a meaningful amount of electricity,” Travis asserts.

The X-57’s additional moniker is an homage to James Clerk Maxwell, the 19th century Scottish mathematician and physicist who pioneered the theory of electromagnetism.

Whether or not the experimental plane gets off the ground, the NASA effort could at least help drive battery and other power management innovations in a market segment requiring maximum reliability and safety.

Self-driving trash can controlled by Raspberry Pi

YouTuber extraordinaire Ahad Cove HATES taking out the rubbish, so he decided to hack a rubbish bin/trash can – let’s go with trash can from now on – to take itself out to be picked up.

Sounds simple enough? The catch is that Ahad wanted to create an AI that can see when the garbage truck is approaching his house and trigger the garage door to open, then tell the trash can to drive itself out and stop in the right place. This way, Ahad doesn’t need to wake up early enough to spot the truck and manually trigger the trash can to drive itself.

The trash can’s original wheels weren’t enough on their own, so Ahad brought in an electronic scooter wheel with a hub motor, powered by a 36V lithium ion battery, to guide and pull them. Check out this part of the video to hear how tricky it was for Ahad to install a braking system using a very strong servo motor.

The new wheel sits at the front of the trash can and drags the original wheels at the back along with

An affordable driver board controls the speed, power, and braking system of the garbage can.

The driver board

Tying everything together is a Raspberry Pi 3B+. Ahad uses one of the GPIO pins on the Raspberry Pi to send the signal to the driver board. He started off the project with a Raspberry Pi Zero W, but found that it was too fiddly to get it to handle the crazy braking power needed to stop the garbage can on his sloped driveway.

The Raspberry Pi Zero W, which ended up getting replaced in an upgrade

Everything is kept together and dry with a plastic snap-close food container Ahad lifted from his wife’s kitchen collection. Ssh, don’t tell.

Software

Ahad uses an object detection machine learning model to spot when the garbage truck passes his house. He handles this part of the project with an Nvidia Jetson Xavier NX board, connected to a webcam positioned to look out of the window watching for garbage trucks.

Object detected!

Opening the garage door

Ahad’s garage door has a wireless internet connection, so he connected the door to an app that communicates with his home assistant device. The app opens the garage door when the webcam and object detection software see the garbage truck turning into his street. All this works with the kit inside the trash can to get it to drive itself out to the end of Ahad’s driveway.

There she goes! (With her homemade paparazzi setup behind her)

Check out the end of Ahad’s YouTube video to see how human error managed to put a comical damper on the maiden voyage of this epic build.

Self-driving trash can controlled by Raspberry Pi

YouTuber extraordinaire Ahad Cove HATES taking out the rubbish, so he decided to hack a rubbish bin/trash can – let’s go with trash can from now on – to take itself out to be picked up.

Sounds simple enough? The catch is that Ahad wanted to create an AI that can see when the garbage truck is approaching his house and trigger the garage door to open, then tell the trash can to drive itself out and stop in the right place. This way, Ahad doesn’t need to wake up early enough to spot the truck and manually trigger the trash can to drive itself.

Sir, yes, SerLCD

Welcome, welcome, welcome! This week we have three products to show off and they are all new versions of our popular serial LCDs. SerLCD was introduced a few years ago to provide an AVR-based liquid crystal display that didn't require a control backpack. Now, we offer two 16x2 displays and one 20x4 display, all controllable with Qwiic!

Don't forget that you can get a free SparkFun Qwiic Pro Micro BoogieBoard with any purchase of $75 or more using promo code "BOOGIEBOARD20" (some restrictions apply). Supplies are running short so get yours before we run out!

Now onto our new products!

Serial enabled LCDs have never been easier to use!

The SparkFun SerLCD is an AVR-based, serial enabled LCD that provides a simple and cost effective solution for adding a 16x2 Black on RGB or RGB Text on Black Liquid Crystal Display into your project. The PCB design on the back of the screen includes an ATmega328P that handles all of the screen control, meaning a backpack is no longer needed! This display can communicate three different ways: serial, I2C and SPI. These versions come equipped with a Qwiic connector, bringing serial LCDs into the Qwiic ecosystem. This simplifies the number of wires needed and allows your project to display all kinds of text and numbers.

If you need something a little bigger than a 16x2 display, you're in luck! This 20x4 Black on RGB Liquid Crystal Display can be added to a project just as easily as the screens above and possesses all of the same features as well - the only difference is its size.


That's it for this week! As always, we can't wait to see what you make! Shoot us a tweet @sparkfun, or let us know on Instagram or Facebook. We’d love to see what projects you’ve made!

Never miss a new product!
