Design a microprocessor system with the following specs:
a. Z80 CPU (20 MHz clock)
b. 32 KB SARM (150 ns access time)
c. 32 KB EPROM (180 ns access time)
d. 8-bit TTL I/P port and 8-bit TTL O/P port, both using the same
address 00
e. Minimal decoding logic
f. Schmitt trigger inverter based Reset & Clock circuits
running at full speed
g. A non-maskable interrupt at a rate of 50 times per second to
carry out routine checks (it does
not have to be very accurate; 1 or 2 less or more per seconds is
fine). Do not use counters or
timers.
h. Make sure timing is proper and use wait cycles if necessary
