It depends on what tasks you plan to solve and how much resources you

From the compiler's point of view you'll spend much time to make an
effective compiler. Look at the DSPs market - do you know many C
compilers which generate instructions for DSP's MAC-unit? which
generate MAC instead of MUL + ADD? i find 0 compilers, which do it
(even for such a DSPs like Motorola 56K, TI etc.). Besides - can smb.
point me to the compilers which do it?
From the other side the problem looks very interesting and contains many
problems, which can be researched.
