Methods

impl Cpu

pub fn new() -> Cpu

Create a new Cpu object.

pub fn reset(&mut self)

Reset CPU states.

pub fn fetch(&mut self) -> Result<u32, Exception>

Fetch the next instruction from the memory at the current program counter.

pub fn translate(&mut self, addr: usize) -> Result<usize, Exception>

Translate a virtual address to a physical address for the paged virtual-memory system.

pub fn execute(&mut self, data: u32) -> Result<(), Exception>

Execute an instruction. Raises an exception if something is wrong, otherwise, returns nothings.
