I wonder how mainframe emulators (that sometimes are used to run legacy, very critical software on modern hardware) manage to do it. Do they go for full complete emulation? As in, implementing the entire hardware in software?
- xcv123 2y agoMainframes typically execute batch processes on a CPU. Much simpler than a game console with a GPU. Cycle-accurate emulation is less relevant for mainframes.
- Locutus_ 2y agoMost of those a JIT recompilers, Mainframe code doesn't usually depend on instruction cycle timing to the level that say beam-racing game code does.
