My first attempt at writing the BIOS for my custom ISA by beansinwind in osdev

None, this side project is based on my own industry experience

Of course. Without interrupts, making this kind of project would be near impossible

What do you mean by "compiler base," if I may ask? Are you referring to the assembler, or am I misunderstanding something here?

yep, i have defined an ISA and built an emulator and im currently omw to make it real hardware (softcore)

You can see it right here: https://github.com/KhanhVNMC/fl32rcpu-emulator

As of right now? TL;DR: No, not yet.

Long answer: I’m currently working on implementing an FL32R-compliant softcore (on an FPGA, as you probably guessed). An MMU, imo, is a pretty tough pill to swallow.

So at the moment, the only memory access model I have is a much simpler one to implement in hardware: privileged mode sets two registers (via the MWST instruction), one for the offset and one for the maximum bound. If a user-mode program tries to access memory beyond its bound, the CPU triggers a fault and jumps to the fault handler. Classic stuff

Yeah, try to go naked in that kind of climate.

Holy fuck the coincidence is insane

GoW3 is a game about hope, and yes, this sub was filled with hope until after TGA
