Description
A 16 bit non-bussed minicomputer design exhibits significant
performance advantages over the popular 8080 microcomputer.
The design and operation of this device is discussed.
Microcoding is employed only where it is a direct
replacement for a needed combinatorial function and
microcode formats are kept as simple as possible. Since it
is anticipated that non-direct addressing will be used
extensively in the eventual application of teleprocessing,
special hardware is committed to this task. The result is a
significant speed advantage over typical address calculating
schemes. Additional circuitry is provided to allow rapid
subroutine entry, exit, and parameter fetching.
