Ask HN: What is the most complex topic you understand?
The Prime minicomputer architecture, from the 80's. Competed with Dec VAX, Data General Eclipse, etc.
The Prime architecture was based on the Multics design from a group of guys hailing from Honeywell and MIT. I worked on Primes for around 12 years, worked for Prime briefly in the 80's, and wrote an emulator that runs many versions of Prime's OS, Primos: https://github.com/prirun/p50em
Prime systems are very much the opposite of RISC, with instructions for:
- process exchange and task scheduling
- procedure call, incl arguments, ring crossing, stack handling, register saves
- decimal arithmetic, incl picture editing for COBOL & PL/I
- string instructions and picture editing
- 6 CPU modes for compatibility with older processors
- DMA, DMC, DMT, DMQ I/O modes for controller access to memory
- 32, 64, and 128-bit floating point
- 2.3k Patch Would Improve Linux Build Times 50~80% & Fix “Dependency Hell”
