zilog z280
an enhanced version of the zilog z80 with a 16 bit architecture, introduced in july, 1987. it added an mmu to expand addressing to 16mb, features for mult-tasking, a 256 byte cache, and a huge number of new op codes (giving a total of over 2000!). its internal clock runs at 2 or 4 times the external clock (e.g. a 16mhz cpu with a 4mhz bus).

zilog z8000 processor a microprocessor from zilog introduced not long after the intel 8086, but with superior features. it was basically a 16-bit processor, but could address up to 23 bits in some versions by using segment registers (to supply the upper 7 bits). there was also an unsegmented version, but both could be extended […]
