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
