BasiliskII Macintosh 68k Emulator Ported to ESP32-P4 / M5Stack Tab5
- swiftcoder 10mo agoHow performant is this - are we able to achieve similar speeds as an actual 68k Mac on embedded hardware?
- iamflimflam1 10mo agoThe P4 is pretty high spec with a 400MHz dual-core RISC-V
- cardanome 10mo agoEspecially as there is a decent working BasiliskII port for the PlayStation Portable with its 333MHz single-core MIPS CPU. So this should be much easier.
- vardump 10mo agoAt 8 MHz, a 68k can execute at most 2M instructions per second. So the answer is going to be yes, if this manages to execute one 68k instruction per ~200 cycles. I think executing an instruction is going to be closer to 20-50 cycles than 200, so it should be much faster than a real 68k CPU. I think performance is likely to be in the ballpark of a 68040 @20 MHz, but that's just a guess. This would leave 20 cycles for each emulated instruction. With JIT you could reach 200 MHz+ comparable speeds.

- bArray 10mo agoLooking at the M5Stack Tab5 IoT Development Kit [1] based on the ESP32-P4 - it's a really nice piece of kit. [1] https://shop.m5stack.com/products/m5stack-tab5-iot-development-kit-esp32-p4 https://shop.m5stack.com/products/m5stack-tab5-iot-developme...
- nottorp 10mo agoYeah, the first thing I thought of when seeing this was "how long till this tablet thingy will be out of stock everywhere?".
- zeckalpha 10mo agoHoping rePalm ends up there, too! https://dmitry.gr/?r=05.Projects&proj=27.%20rePalm https://dmitry.gr/?r=05.Projects&proj=27.%20rePalm
- jhbadger 10mo agoPity that this isn't for the Cardputer (a M5Stack device that includes a built in (tiny) screen and keyboard), although it might be impractical on it.
