[sdiy] Raspberry pi(e)

[Jay Schwichtenberg]

Mark,

At least you had chips. The Classic PDP8 and CDC3300 I had in college were
discrete.

There are a number of people at work that are interested in this. From what
they've said it's been delayed some and they haven't gotten them yet.

Yeah neat kit :).  The amount of cool stuff it can do is not to be under
estimated...  A decent intel core 2 duo uses over 50% of its processor to
decode HD vid (720p), this part does that and runs android at the same time.

Can't wait for them to release apple pi, the dual A9 version <grin>

(I made that up...I mean imagine kids working on programming modern ARM
cores, I had to do college with a 6502 board....)

Hi Mark :)

*waves*

Yeah, its a BCM2835 Apps Processor: Videocore4 with an ARM11 and, for
the Raspberry Pi, 256MB of SDRAM on top.  For audio you either have
the ARM to play with, or if you can stomach it you can write fragment
shaders to do 2D data processing at much faster speeds.  OpenCL is not
available so it'll be old-fashioned OpenGL shader code, which is a bit
hacky but works:
