CPU in digicams

[Pelle1948]

I have found some info (really not much) about Bionz used by Sony:

http://en.wikipedia.org/wiki/BIONZ
http://www.sony.com.sg/microsi...slr/features_ch06.html
http://www.dpreview.com/reviews/sonydslra900/page3.asp

Anyone knowing more about what kind of CPU they normally use today in digicams?
The requirements are high indead and Sony needs two CPUs for the 24 mpixel big DSR camera. Is it a kind of DSP or a GP processor like ARM or Intel Atom?

Yeah there's not much info about Bionz. I'm guessing Canon's DIGIC is similar and wikipedia has a lot more info on that:

http://en.wikipedia.org/wiki/DIGIC

The DIGIC board contains x86 compatible processor (NEC V30 emulation) running Datalight ROM-DOS[6] and two other chips (the image processor itself and Motorola 68HC12).[7]

The DIGIC II and DIGIC III ASICs contain embedded 32-bit ARM architecture processors. Until around 2007, Canon point-and-shoot cameras ran a VxWorks-based operating system, but recent cameras are based on the DRYOS operating system developed in-house by Canon.[citation needed]

Thank you very much for that info about DIGIC from Canon!

DSP is of course very important and I have found this:

http://en.wikipedia.org/wiki/DSP_Chip

Embedded general-purpose RISC processors are becoming increasingly DSP in functionality.
For example, ARM Cortex-A8 has a 128-bit wide SIMD unit that can have impressive
16- and 8-bit performance for industry standard benchmarks.
