I'm confused. Holding DTACK/ unasserted (high) doesn't interrupt the program, it just prevents the memory cycle from completing until DTACK/ is asserted (low). It's like WAIT on other processors. Why would you need an instruction-interruptible core to emulate that?
You're confusing interrupting the guest program with interrupting the host program. For most CPU cores in MAME, as with most emulators, the emulation of an instruction runs to completion before there can be any further outside influence on the emulated CPU's state.
The memory fetch occurs, and that's it. There's no facility for saying, "Whoa, wait, break out of the current timeslice for which the emulated CPU is running, and service the other running devices for now instead" while the memory-read instruction is still in-flight.
This is an issue with the Z80 as well. The 6502 and a couple of other CPU cores in MAME, however, do support being suspended mid-instruction.
Thanks for explaining.
Anytime. There's a lot of MAME-specific terminology that we MAME devs sling around without necessarily considering that the terms might be synonymous with other, more common, concepts.
