[sdiy] Using 8051 to build a synth

[phillip m gallo]

The integration of mixed signal components proceeds across most of the
microcontroller devices resulting in a wealth of choices for possible
platforms.  These platforms execute at increasing transaction rates as
processes mature and evolve onto new process technologies.  Integrated
memory and devices are now well implemented and truly useful for signal
processing.

While the MIPS ratings of processors can be a fallacious indicator in
general, for specific case signal processing (where known algorithms
implement to produce a given result) it can combine with an analysis of
the specific hardware implementation; i.e. how do i write the DACs,  is
their an integrated MAC,  how will i achieve determinism, what
architectural implications exist  (stack handling, depth, interrupts);
to allow an informed choice of a specific platform for a specific task.

It is a great era in mixed signal controllers.

regards,
p

Hi,

>Down side of the AVR is maximum clock speed, tops out at 16 Mhz or so.

Actually, it's quite good.. At 16 MHz, the AVR series reach up to 16
MIPS 
while a PIC can only get to 4 MIPS @ 16 MHz because it uses 4 clocks per

instruction cycle.. At least that is what I seem to read in the 
datasheets.. 8) But I might be reading them incorrectly..

Cheers,
Niels..
