The Central Processing Unit status and registers

Implementations

impl Cpu

CPU Addressing Modes

The 6502 can address 64KB from 0x0000 - 0xFFFF. The high byte is usually the page and the low byte the offset into the page. There are 256 total pages of 256 bytes.

Trait Implementations

impl Clock for Cpu

fn clock(&mut self) -> usize

Runs the CPU one instruction

fn clock_to(&mut self, _clocks: u64)

impl Clone for Cpu

fn clone(&self) -> Cpu

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Cpu

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Cpu

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Mem for Cpu
