sep8emulator
sep8 emulator is a C++ emulator for the didactic processor called sep8, as described in this book.
Implemented features:
-
CPU loop supporting decoding of the entire instruction set described in the book
-
IO system supporting following operations:
- Blocking mode
- Interrupt mode
- DMA mode
-
IO Devices implemented:
- APIC with programmable interrupt handlers for each IR entry
- HDD (block device) with SATA-like interface (supports DMA mode) emulated on file
- Dummy device (random number generator)
-
Extras:
- Assembler written in python: enable high-level (assembly-like syntax) language to machine-level language assembly
- Example programs:
- BIOS: load super-simple OS from HDD using DMA operation
- Some interrupt gates
- User space program that does some IN/OUT operations using INT service requests.
Instructions
In order to execute the emulator with example programs:
make all ./run -l
