Struct intel_8080_emu::proc_state::Proc8080

pub struct Proc8080<Bus: DataBus> { /* private fields */ }

Structure containing the processor state (flags, registers and memory) and logic.

Implementations

impl<Bus: DataBus> Proc8080<Bus>

pub fn new(mem: Box<[u8]>, data_bus: Bus) -> Proc8080<Bus>

Builds a new Proc8080 with the given memory mem and DataBus.

The memory contains both the ROM and RAM of the processor. Usually it is called with a boxed array of size 0xffff (adressable space for the intel 8080) which contains the ROM at the beginning of the memory. The processor starts with the program counter equal to 0.

The data_bus contains callbacks called when running a IN or OUT opcode.

pub fn flags(&self) -> &Flags

Borrows the procesor flags immutably.

pub fn registers(&self) -> &Registers

Borrows the procesor registers immutably.

pub fn emulate(&mut self)

Reads the next opcode in memory and changes state accordingly.

This methods run one step of the processor simulation. It reads the next opcode according to the program counter

pub fn memory(&self) -> &[u8]

Borrows the memory immutably.

pub fn interrupt(&mut self, rst_value: u8)

Make the processor run a RST instruction.

There are 8 possible RST instruction for the 8080 (RST 0 to 7). The specific instruction is chosen via rst_value.

An interrupt restart a processor which was in stopped state after running a HLT opcode.

Panics

If rst_value is greater than 7;

pub fn cycles(&self) -> u64

Cycles elapsed since the cpu was created

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

Formats the value using the given formatter.
