9086

A CPU that aims to be binary compatible with the 8086 and with as many optimisations as possible

Progress

  • Executing code
  • Is Turing complete
  • Can boot up MS-DOS / FreeDOS
  • Is completely binary compatible
  • Is pipelined
  • Is Out of Order
  • Is superscalar

Building it

To build it you need Icarus Verilog, bin86, GNU make, xxd and the posix coreutils. Go into the cpu directory and run make

At the time of development the versions used are :

  • Icarus Verilog version 11.0 (stable)
  • bin86 version: 0.16.17
  • GNU Make 4.3
  • xxd 2022-01-14
  • GNU coreutils 8.32
