and are 2 different tags. Should they be merged since these terms are often used interchangeably?

    \$\begingroup\$ If they are merged, I think we should keep "processor" as it is the more generic term. \$\endgroup\$ Jul 9, 2021 at 23:00

    \$\begingroup\$ Is 'processor' used on any significant questions where 'microprocessor' would be wrong? Is anybody asking about PDP-8s. If not, then keep the more popular microprocessor, and ditch the outdated processor, generic though it is. \$\endgroup\$

    \$\begingroup\$ As long as we have 'microcontroller' and 'microprocessor' as distinct tags, that covers most use cases. The exception would be for the folk on the Retrocomputing stack, which interestingly does not have a 'processor' tag. \$\endgroup\$

Every microprocessor is a processor, but not every processor is a microprocessor.

    \$\begingroup\$ Do you have concrete examples of a processor that would not be a microprocessor? The ENIAC maybe? How often are these very devices mentioned in EE.SE questions? How often has "processor" been used when it could not be "microprocessor"? How often is "processor" used when it could actually be "microprocessor"? As I see it, the actual consequence of having two separate tags is that somebody who follows "microprocessor" misses a big chunk of the questions he's interested in. \$\endgroup\$

  • \$\begingroup\$ FPGA, programmed as such? An analog filter? I'd say "processor" is almost a meta tag. \$\endgroup\$ Jul 19, 2021 at 13:02
  • \$\begingroup\$ Even microprocessor is too meta, we already have CPU tag @dim \$\endgroup\$ Jul 19, 2021 at 13:53
  • \$\begingroup\$ Microprocessor is a fine tag. When you use it, everyone knows exactly what you're talking about. CPU may or may not be. I suspect it's fine, and more pertinent to questions dealing with architecture. Processor, in and of itself, means little. I'd nuke processor, maybe completely editing to change it to microprocessor after scanning all 109 (!!!!!!!!) questions so tagged. \$\endgroup\$ Jul 19, 2021 at 14:09

    \$\begingroup\$ Back to examples -- ACSL was a processor, converting ACSL statements to Fortran. A compiler is a processor that converts computer language to machine code. The term is just too vague to be a useful tag. \$\endgroup\$ Jul 19, 2021 at 14:40
  • \$\begingroup\$ @ScottSeidman What exactly is a microprocessor? I know what a CPU is \$\endgroup\$ Jul 20, 2021 at 3:47
