lrvm crate

The lrvm crate contains the core of LRVM: the motherboard and components emulation, as well as the CPU and the MMU.

It is split across several main types:

  • board::MotherBoard is the virtual motherboard type
  • mem::Mem is the virtual motherboard's mapped memory
  • board::Bus is a trait components must implement in order to be connected to the motherboard
  • cpu::CPU is the virtual CPU
  • cpu::Regs represent the registers of the virtual CPU
  • mmu::MMU is the virtual MMU (Memory Management Unit)

If you want to make use of this crate, you can take up the tutorial to see how to build a virtual machine, assemble a program and run it with debugging tools.

You can find a collection of useful auxiliary components in the lrvm_aux crate.

There is also a set of tools to deal with the VM (including a complete assembler and a set of debugging tools) in the lrvm_tools crate.

You can find more details about LRVM's architecture in the architecture document.
