Are You Ready for PCIe 6.0?

I don’t know about you, but I’m starting to feel a little frazzled around the edges, as it were. Things are now progressing so fast that I’m finding it difficult to keep up. I still hear people boasting “We now support PCIe 4.0,” even though PCIe 5.0 is roaming wild and free, and now the folks at Rambus are briefing me on their PCIe 6.0 offerings. Pass me my smelling salts because I’m too young for all this excitement!

Just to ensure that we’re all tap dancing to … Read More → "Are You Ready for PCIe 6.0?"

A History of Early Microcontrollers, Part 1: Calculator Chips Came First

Gary Boone, who worked in the Texas Instruments (TI) MOS Department, devised the first chip that can be called a microcontroller because he was becoming bored with his job and in trouble with his family. He’d joined TI in 1969 just when calculator chips were getting to be big business. During the 1960s, electronic calculators replaced the electromechanical Marchant and Frieden calculators that had owned the market for decades. Semiconductors made it possible to replace the hundreds of intricate metal and plastic parts in these electromechanical calculators, first with hundreds of transistors and diodes, and then … Read More → "A History of Early Microcontrollers, Part 1: Calculator Chips Came First"

Will X9 Spider Computer Systems Power the US Army in 2030?

A couple of weeks ago as I pen these words, I heard that the folks from General Micro Systems had taken home three “Best of Show” awards from the recent AUSA 2022 annual meeting and exposition, which was held 12-12 October in Washington DC, and whose purpose was to highlight computing innovations for building the Army of 2030. … Read More → "Will X9 Spider Computer Systems Power the US Army in 2030?"

In Memoriam: Dave Cochran, an Engineer’s Engineer

Sadly, my friend Dave Cochran passed away on October 7. You’ve likely never heard of Dave Cochran, but if you ever owned a scientific calculator, you owe him, big time. Cochran was “Mr. Algorithm” at Hewlett-Packard starting with the earliest days of HP’s desktop scientific calculators in the late 1960s. He developed the arithmetic and trigonometric algorithms for HP’s first calculator, the HP 9100A desk calculator, using numerical calculation methods and approximations that had been around for hundreds of years. Then Bill Hewlett pestered him regularly for years until Cochran and his colleagues at … Read More → "In Memoriam: Dave Cochran, an Engineer’s Engineer"

DARPA Funds Space Lasers to Bring Non-Sectarian Internet Communications to Outer Space

Have you noticed that low-Earth orbit (LEO) is getting crowded? Several companies are developing globe-spanning satellite networks to provide Internet access to every square inch of the Earth’s surface. Elon Musk’s SpaceX and Starlink may be the most visible venture, but other entrants in this derby include Amazon’s Project Kuiper, SpaceLink, Viasat, and Telesat. On the one hand, it’s going to be very handy to have multiple companies competing to spread Internet-based communications everywhere. On the other hand, there’s an issue of compatibility that’s raising its ugly head. All of … Read More → "DARPA Funds Space Lasers to Bring Non-Sectarian Internet Communications to Outer Space"

O-M-Gosh, I’ve Been Zeked! (Part 3)

As you may recall from my previous “O-M-Gosh, I’ve Been Zeked!” columns, 11-year-old Zeke is on a mission to talk to the astronauts and cosmonauts orbiting the Earth on the International Space Station (ISS). He started by getting his ham radio license when he was only 8 years old, and now he’s working on getting his 10-foot helical antenna to track the space station. … Read More → "O-M-Gosh, I’ve Been Zeked!

How Long Until We See Whales in Classrooms?

Do you remember all the hoopla about the company Magic Leap a few years ago? I’m trying to remind myself of the timeline. The company was founded in 2010 but was in stealth mode until around 2015. In 2016 they released a teaser video that showed what purported to be augmented reality (AR) in the form of a whale surprising school students by jumping into a gym. … Read More → "How Long Until We See Whales in Classrooms?"

Looming Crypto Crisis Rides In With Quantum Computing

It seems, increasingly, like writing technology articles is becoming nothing more than covering a long list of unfolding crises. The crisis du jour is the imminent breakdown of cryptographic security, thanks to the expected arrival of quantum computers. Today’s cryptography relies heavily on implementations of RSA public-key cryptography, which is now used pervasively for data encryption and decryption in networking and computing. RSA encryption – named after its inventors: Rivest, Shamir, and Adleman – relies on the difficulty of decrypting the encoded data without a key, which requires some bodacious math to factor large numbers if you … Read More → "Looming Crypto Crisis Rides In With Quantum Computing"

Meet UVVM: The World’s #1 VHDL Verification Methodology

I’m happy (albeit puzzled) to tell you that things seem to be getting better with respect to verifying FPGA, ASIC, and system-on-chip (SoC) designs. The reason I say this is that the last time I turned my attention to this arena, people were saying that the design and verification phases of a complex device consumed 30% and 70% of the total development time, respectively. By comparison, someone recently informed me that these numbers are now more like 50% and 50%, which means either we’ve become better at doing verification or worse at doing design.
