Does it not follow the APCSish concept (R13=sp, R14=lr, R15=pc, etc)?
Are the general register assignments different?
Even so, it still ought to _look_ like ARM code in the same sort of way
that Thumb does.
Speaking of which... just done some research. My little PVR woefully
underutilises a TI DSP/ARM combo (TMS320DM320). It is running an ARM926.
Oh, and my Creative Zen is ALSO running an ARM926, and to play MP3s it
gets ~25 hours on a Li-Ion cell. :-)
Somewhat ironic that the bog-standard generic thingy that replaced my
video recorder could not only in theory run RISC OS, it could kick any
RiscPC's butt up and down the country - the subsystems clock 160 or
180MHz (depending on your source) while the CPU is a fairly sedate
320MHz. As opposed to the <cough>40</cough> of the ARM7.
