yes, Imagination will definitely compete with ARM's CPU-GPU in the mobile segment.

How is MIPS right move in the 3.5G-4G as reported by you going? Value of MIPS patents was value of MIPS patents when Sandeep Vij took over. Business sold for $60M - what a debacle. Blind trust in a mediocre executive by a reporter and being a free advertising vehicle is probably not considered good reporting.

Microchip is selling a MIPS-licensed core as PIC32, and I don't see them going to ARM.

I'm guessing ARM bought MIPS for their Simultaneous Multithreading (SMT or "Hyper-threading") know-how. ARM has steadfastly refused to implement SMT (and made some grossly inaccurate statements about SMT's power/perf) despite the fact that practically every other new CPU on the market (including Intel Medfield) has it. When ARM eventually does implement SMT they'll probably refer to it by something like "Argon Mist" and claim that it's unique to the industry.

I concur.

The summary is: MIPS is dead. ARM won. ARM will commoditize everything. We all EE will lose our jobs and have to work in some other non-tech industry.

MIPS will not be completely dead, more like a zombie or the walking dead. It will still be used like PowerPC and SH are still used but no longer one of the mainstream high profile application processors like Intel and ARM. It may once again come back to life but it would require backing by a major player with deep pockets. China could have run with MIPS but they have a weak track record with software. MIPS died because it lost the critical mass software support like Intel and ARM retain. If you don't have the software ecosystem and application developers your hardware is useless. Yes, MIPS did have software support but it was declining badly and getting left behind by ARM and Intel. Worse MIPS was eating majority of that software development cost themselves. Their biggest customer Broadcom was not helping them at all in this area. Meanwhile ARM and Intel have built armies of software developers supporting their ecosystems and even better they are subsidized by their deep pocket customers. For example, ARM has Google and Linaro (i.e. TI, Samsung, IBM, Freescale), and Intel which doesn't even need subsidizing has enterprise server guys (e.g. IBM, RedHat, Novell, Oracle, Dell, ..). And that's not including all the open source guys and smaller companies working for free. Also, MIPS didn't have a cheap development board which open source software hackers could support. All the Linaro guys have cheap development boards for Android and Linux hackers to work on. Cheap Intel boxes are everywhere. What did MIPS software guys have to work on that cost less than $300? Nothing!!! MIPS's customers like Broadcom don't offer cheap development boards only expensive closed proprietary reference designs. Yes, MicroChip has the PIC32 but that's a very low end MIPS core which requires their proprietary toolchain. Now compare that to a $35 Raspberry Pi (ARM-based) that is powerful enough to run Linux. Moral of the story is its all about the software people.

LATEST ARCHIVED BROADCAST
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
