Mmm, that would be telling.  All we do is make the silicon for each of
our products work as well as we possibly can.

I don't think that the instruction set has been publically released yet
however there are some design issues that make the chip interesting.
It is a Harvard architecture part that uses a 12 bit instruction path and
a 8 bit data path. In general it can execute at one clock per instruction
with the usual delays on branches. Close to 50 MIPS is available from
the part. Memory management for both RAM and ROM is very clean and
simple.  The part has interrupt support and basic context restore as
part of the hardware.

The Electronics Design (Aug 4/97 cover story) article gives a
overview and use of the hardware. The part basically uses software
to create I/O devices that are normally built in hardware. It trades
processor bandwidth for hardware complexity. The same part can
be used for many different applications  Programming and debugging
is done through the external OSC pins on the part.

SXC is one of the new Windows, DOS and UNIX cross compilers
we will release this fall. SXC is fully compatible with all of the Byte
Craft 8 bit embedded system development tools,
