I agree with "logic" or "digital logic". Such circuits are comprised
of logic chips -- CMOS logic, TTL logic, etc etc. from one or more
compatible logic "families".
A microprocessor is different than a logic chip because it requires a
program to define its function. A processor or computer can certainly
be contstructed using logic chips but it will also necessarily contain
memory and would then be regarded as a system or at least subsystem.
Glue logic is usually describes the gates between
a microprocessor and something else. I'd use the
term "random logic" (kind of an oxymoron) to describe
a logically functioning set of parts without a
I began with gates made from 2N104 transistors, some in birdcage
assemblies. A complex machine like a phase-shift modem was the size of
a dishwasher, filled with cards containing two gates each. The
designers really earned their pay back then, modern stuff is more
complex but less clever.
So few of us made it all the way through school that the Army gave up
on training techs for component-level troubleshooting of that
equipment. The four (of ~100) in my graduating class all had science
Except that these days you can slap an FPGA on a board, put a
configuration file in it, and common usage will call it 'logic' -- even
though the FPGA has memory in it. Sometimes, even though the FPGA
configuration has a microprocessor hidden in it.
The lines are blurred.
(Note that I am only commenting on usage as I've heard it: were I a
linguist I would claim that a language is what is spoken, not what the
people in ivory towers say _should_ be spoken).
