Power delivery networks (PDN) are the metal structures on a chip that delivers the power. In a high-end desktop SoC this might be delivering as much as 150W, and with voltages around 1V that means over 150 amps of current. Clearly getting the PDN correct is critical for a correctly functioning chip. One of the challenges to verifying… Read More
Sonics have been building networks-on-chips (NoCs) for a long time and have amassed a rich patent portfolio. So being granted a new one isn’t usually deemed press-release-worthy. However, their latest patent on power management is pretty significant. It is patent 8,601,288 titled “Intelligent Power Controller”.
Historically… Read More
Every ASIC company has a major challenge: they have to work out what it is going to cost to build the customer’s product and commit to deliver it at that price. Too high and you lose the business. Too low and you will wish you’d lost the business. Historically this has been done largely manually. This is an expensive process.… Read More
Atmel was founded in 1984. The name stands for “advanced technology for memory and logic” although initially the focus was on memory. George Perlegos the founder had worked in the memory group of Intel back when Intel was a memory company and not a microprocessor company although that didn’t stop Intel suing… Read More
It is microprocessors all the time right now, with Linley last week. Today ARM announced the next generation Cortex-A17 core. It is a development built on the Cortex-A12 core, itself built on A7 (which is the current volume leader). ARM says that it is 60% faster than the A7 core, although I’m sure a lot of that gain is a process… Read More
Cadence today announced that it is acquiring Forte Design Systems. Forte was the earliest of the high-level synthesis (HLS) companies. There were earlier products. Synopsys had Behavioral Compiler and Cadence had a product whose name I forget (Visual Architect?), but both products were too early and were canceled. Cadence … Read More
TSMC doesn’t just sell wafers, it sells trust. It’s the Colgate Ring of Confidence for fabless customers. This focus on trust started at the very beginning when Morris Chang founded TSMC over 25 years ago, and still today trust remains an essential part of their business.
When TSMC started, the big thing it brought … Read More
Did you know that an S-class Mercedes Benz can use 100 microprocessor-based electronic control units (ECUs) networking throughout the vehicle that run 20-100 million lines of code (Source: IEEE)?

Here’s a quick list of all the places that you will find software controlling hardware in an automobile:… Read More
Networks-on-chip (NoCs) are very configurable, arguably the most configurable piece of IP that you can put on a chip. The only thing that comes close are highly configurable extensible VLIW processors such as those from Tensilica (Cadence), ARC (Synopsys) and CEVA but Sonics would argue their NoCs are even more flexible. But … Read More
You may know a bit about Bitcoin, the digital currency. One part of the system is “mining” new bitcoins, analogous to mining new gold when we were on the gold standard, creating “money” out of thin air but at a cost of doing the actual mining.
Here is an interesting aside. When I lived in France the father of… Read More
