What I like about "single-chippers" is that
you have the option of
looking
at them as programmable logic. They're not all as
fast as CPLD's, but
they're generally not as costly as a CPLD or FPGA capable of duplicating
their function. A Z80 CPU or one of its scions compatible with its
instruction set would still require external hardware to provide the
interface to read-write memory, then the memory itself, and the decoding
for
When I say "core" for a gate array I mean one of those large ones that
can also provide the needed ram, rom and IO. As in ASIC.
I almost did a job where the cpu core was 80C88, really hate that CPU
and am glad I didn't.
