Expand description

The CPU’s state, which is what gets ticked.

Fields§

§a: u8§f: Flags§b: u8§c: u8§d: u8§e: u8§h: u8§l: u8§pc: u16§sp: u16§ime: bool§cycles_elapsed: usize

Total number of M-Cycles that have passed during this CPU’s life.

§address_space: S

The address space the CPU is communicating with.

Implementations§

impl<S: AddressSpace> State<S>

pub fn new(address_space: S) -> Self

pub fn get_af(&self) -> u16

pub fn get_bc(&self) -> u16

pub fn get_de(&self) -> u16

pub fn get_hl(&self) -> u16

pub fn set_af(&mut self, value: u16)

pub fn set_bc(&mut self, value: u16)

pub fn set_de(&mut self, value: u16)

pub fn set_hl(&mut self, value: u16)

pub fn get_r8_by_id(&mut self, id: u8) -> u8

pub fn set_r8_by_id(&mut self, id: u8, value: u8)

pub fn read(&self, address: u16) -> u8

Passthrough for self.address_space.read().

pub fn write(&mut self, address: u16, value: u8)

Passthrough for self.address_space.write().

pub fn tick(&mut self) -> TickResult

Steps the CPU forward by one instruction. self.cycles_elapsed is updated accordingly.
