Chris Rowen of Cadence’s Tensilica announced the tenth generation of the Xtensa customizable processor at the Linley Microprocessor Conference yesterday. Chris was one of the founders of Tensilica…back in 1997. I believe that the first version was released in 1999. Over the years the Tensilica business changed.… Read More
Since Imagination’s acquisition of MIPS at the end of last year, the MIPS product line has been given a new lease of life. There are two things driving this. The first is simply that with its new home, the MIPS architecture has a solid future whereas before it was uncertain. Secondly, Imagination moved their own general purpose… Read More
Imagination seems to be well known for a couple of things. Firstly, everyone knows that it is the graphics processor used in the iPhone and the iPad and lots of other phones. And they know that Imagination acquired MIPS at the start of this year.
But what people don’t seem to really appreciate is just what a huge portfolio of IP… Read More
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
It has been a little over a fortnight since Paul Otellini officially stepped down from the CEO post and yet it seems to be more than a long time gone. Unlike his predecessors, he was not asked to remain on the board and perhaps it is a sign that his complete disengagement from the company was necessary to complete a future strategic engagement.… Read More
At a dinner table a couple years ago, someone quietly shared their biggest worry in EDA. Not 2GHz, or quad core. Not 20nm, or 450mm. Not power, or timing closure. Call it The Rollover. It’s turned out to be the right worry.
Best brains spent inordinate hours designing and verifying a big, hairy, heavy breathing processor core to do … Read More
It is obviously a truism that somewhere in an SoC there is something limiting a further increase in performance. One area where this is especially noticeable is when a Tensilica core is used to create a highly optimized processor for some purpose. The core performance may be boosted by a factor of 10 or even as much as 100. Once the core… Read More
The Linley group is the go-to source for information about the microprocessor market. If you go back to their roots in Michael Slater’s Microprocessor Report then they have been in the business for 25 years. We haven’t had microprocessors for that much longer. They just tagged Tensilica as being second in shipments… Read More
When Intel entered the server market in the 1990s with their Pentium Processor and follow on Xeons beginning in 1998, they focused on the simple enterprise applications. At the same time they laid the groundwork for what will turn out to be a multi-decade, long war to wrest control from all mainframes and workstations. The announcements… Read More
Back in the 2008 financial Crises, GM was finally brought to its knees and had to face a radical makeover. They asked for a bailout from the government that allowed the unions to swap out lower compensation for equity, something no union would do unless the alternative was to shutter the doors. The bondholders and the shareholders… Read More
