We have already discussed the recently released M-PCIe ECN from PCI-SIG in Semiwiki at the end of 2012, but the new “standard” (in fact an Engineering Change from PCI-SIG and MIPI Alliance) was only real on paper, at that time. The upcoming webinar from Synopsys, M-PCIe: Utilizing Low-Power PCI Express in Mobile Designs, shows … Read More
How to Benchmark a Processor
How do you benchmark a processor? It seems like it should be easy, just run some code and see how fast it is. Traditionally processors were indeed benchmarked by raw performance like GMACS, GFLOPS, memory bandwidth and so on. But in today’s world where systems have become very complex and applications very compute intensive, the… Read More
Pre-verified, Integrated Sensor IP Subsystem?
Last year, I said that the launch of ARC based complete sound system IP by Synopsys ring the bell for the opening of a new IP market segment, the “Subsystem IP”. This week, Synopsys has announced the availability of the DesignWare® Sensor IP Subsystem, a complete and integrated hardware and software solution for sensor control applications.… Read More
♫ IMG Sitting on the DOK of the Bay…Closin’ Timin’
Scott Fitzgerald is supposed to have said “the rich are not like other people” to Ernest Hemingway (he didn’t). In the same way, processors are not like other blocks, and not because they have more gates (they don’t). However, special approaches to optimizing processors are important because the clock… Read More
Debugging Verification Constraints
In his DAC keynote last year (2012) Mike Mueller of ARM compared how much CPU was required to verify the first ARM versus one of the latest ARM Cortex CPUs. Of course the newer CPU is hundreds of times larger than the first ARM but the amount of verification required was millions of times as much, requiring ARM to construct their own datacenter… Read More
Can we really find a way to speed-up Processor & DSP core designs?
Once upon a time, ASIC designers involved in Processor design, like I was, for the first time in 1987 for Thomson CSF and again in 1994 for Texas Instruments, at that time supporting height (8) ASIC designed by another French company, the Advanced Computer Research Institute (ACRI), had to re-invent the wheel almost every day. When… Read More
Are you going to the plug fest?
PCI Express 3.0 specification is 1000 pages long. Most of us, and most of the designers integrating PCIe gen-3 into their latest ASIC, FPGA or system will probably never read it completely, or even open it. In fact, they don’t need to read it completely, but they should care about one point, whether they buy an ASSP or a PCIe design IP:… Read More
Happy Birthday to Synopsys VIP
I met Mike Sanie around DVCon time and planned to write a blog about the one year anniversary of Synopsys Discovery VIP which was announced during Aart’s keynote at DVCon in 2012. Eric covered it for SemiWiki here. But Synopsys had other stuff they wanted me to blog about and so it is a couple of months late. The 14th month anniversary… Read More
PCI Express IP vendor Cascade acquisition by Synopsys…
… is now 8 years old, and the money paid for this 10 engineers start-up was considered, at that time, as a “bingo” for Cascade’s funders: “In October 2004, the Company completed the acquisition of Cascade Semiconductor Solutions, Inc. (Cascade) for total upfront consideration of $15.8 million and contingent consideration of … Read More
In compliance we trust, for integration we verify
So, you dropped that piece of complex IP you just licensed into an SoC design, and now it is time to fire up the simulator. How do you verify that it actually works in your design? If you didn’t get verification IP (VIP) with the functional IP, it might be a really long day.
Compliance checking something like a PCIe interface block is a … Read More
