Intel 8080 emu
An intel 8080 emulator library (another one). Initially implemeted to build a space invaders emulator (another another one).
This library provides provides utilities to parse 8080 binary and simulate an 8080 microprocessor. All op codes are implemented and there is no external dependencies.
The main struct is
intel_8080_emu::proc_state::Proc8080. It needs basically two things to work :
- The memory, a simple
Box<[u8]>containing the rom and the ram.
- A structure implementing
intel_8080_emu::proc_state::DataBuswhich handles the
use Proc8080; use MyCustomDataBus; use std; // load your rom as an array let rom: = load_rom; // copy the rom into the 8008 memory let mut memory = Boxnew; memory.copy_from_slice; let i8080 = new; // we're ready ! // Here is naive way to slow down the simulation so that it matches the original speed of the 8080 let mut states = i8080.states; loop
- Maybe better memory handling. It is currently a simple
Box<[u8]>and does not distinguish between ROM and RAM.
