I continue to argue (although of course I have no empirical proof
yet) that compiled SAOL for accelerated architectures will be
faster than compiled C, and at least competitive with hand-coded
assembler, on equivalent algorithms. Particularly for DSP
architectures, a SAOL program embodies the assumptions made by
the hardware much more effectively than does a C program,
and the fundamental processing units of SAOL (delay lines,
signals, table read/writes) are exactly those that map most
effectively onto a DSP implementation. Because of this, it
will be easier to write very effective optimizing compilers
for SAOL->DSP than is C->DSP and especially C++->DSP.
I wonder if some of the folks (John, Giorgio) that have been
working on compiled SAOL implementations could comment on this?
Best,
