In the News The desktop and laptop world is dominated by x86, the mobile/embedded world by ARM. Conventional wisdom, right? Not really. There's also MIPS - hundreds of millions of embedded devices run on MIPS, and for years now, the architecture has been trying to break into the mobile world dominated so much by ARM. They just a got a boost: MIPS has been acquired by Imagination Tech, most known for its PowerVR graphics chips used in a lot of smartphones and tablets.

Aha, great. Grab the MIPS datasheets while you can...

+1, PowerVR is probably one of the few brands in the semiconductor industry that makes things harder than Qualcomm for OS developers.

Consider the Raspberry Pi story: the team was persistent enough to get a TRM from Qualcomm, of all things, and yet Linux on the RPi still relies on binary blobs for GPU operation...

This is something work life has taught me about companies and communities.

It doesn't matter if certain software is made open source or if a given company is geek friendly.

This will only exist as long as the main developers or main company is able to stay in business.

If business fails, patent actions happen, or the company gets bought, then it is the end. Period, nothing to do about it.

So in the end we can only enjoy technology, regardless of the owning company, but with a critical consumer voice.

Sure, and in other news, Apple could ask App Store devs to pay 1200$/year and steal 80% of their profits and the average sheep would still buy iOS stuff as long as his favorite fart app remains available on it.

This is a geeky website, so we put higher importance on stuff which geeks care about. No need to bring up the average guy argument of "only thing that matters in the end is whether it will sell" on a discussion about MIPS manuals, after all Joe Sixpack has probably never even seen the MIPS name somewhere anyway.

Big errata: If we are talking PowerVR, Ti SoCs (which traditionally come with extensive documentation of anything but the GPU) would be a better example. Turns out RPi uses a Qualcomm GPU, so that's just Qualcomm being dicks again by purposely giving out incomplete manuals.

RPi GPU is made by broadcom. Or is broadcom brand of Qualcom?

Its nice GPU where (almost) whole gpu driver reside in firmware. Nice because porting to new OS require just (comparatively) small layer able to feed and gather data. Not nice since, its closed source, and hence Linux Kernel devs will not accept any open source parts.

RaspberryPI is based on Broadcom's SoC with Broadcom's VideoCore4 GPU. Broadcom is not Qualcomm, though not much better then Qualcomm.

This is why I should never post anything on the web when I'm too tired to keep highly focused on something (such as the RPi FAQ) for more than a few minutes :/

Apologies for the double-fail everyone.

NVM the Qualcomm/Broadcom mixup - it seems that the design bureau of the Broadcom SoC used in RPi is a stone's throw away from Raspberry Pi HQ: http://en.wikipedia.org/wiki/Alphamosaic
Also, IIRC, one of the ~historical ~heads of RPi works at Broadcom now.

Both were probably important factors in SoC choice (not so much "going Broadcom despite the troubles", more "keeping it close to home")


PS. This news, of Imagination Tech acquiring MIPS, is probably also about "family business" - this time, a bit of a turmoil in the family. After all ARM Ltd. bought, not a long time ago, some Norwegian GFX fellows - That's where ARM Ltd. got Mali GFX cores.
Meanwhile, Imagination Tech was and still is a major provider of GFX cores in ARM ecosystem. So it's ARM Ltd. who kinda threw the gauntlet here?
