Can you use SPE's in user created programs on PS3 Linux?

Is this possible?(the title)

Would you have to be programming in PPC assembly or what language can interact with the SPE's

C with SPU extensions or SPU assembly. You can read all about it here: http://www.ibm.com/developerworks/power/cell

Just google for things like this, this is all pretty basic stuff...

Some basic examples are here:

All major PS3 llinux distros have spu-gcc compiler and libspe runtime included.

The spe programming language is primarily C/C++. There are assembler intrinsics for high-perfomance code. If you want to write good spe code you must study this doc: http://www.ief.u-psud.fr/~lacas/Compute ... ns_v20.pdf

Thanks a lot everyone. I do want to start programming the SPU's but... Does anyone have an idea once the ps3 fades away, would me SPU programming knowledge have any use at all? Will the ps4 use cell?

Since we seem to have hit some local peak in CPU core clock speeds and the temporary fix seems to be to add more cores, then it certainly won't hurt to learn how to program SPU. More importantly though it will change the way you think about algorithms for processing massive amounts of data.

Thanks Jim... Im going to do some more research on linux/spu related things.
