Struct iz80::Cpu

pub struct Cpu { /* private fields */ }

The Z80 cpu emulator.

Executes Z80 instructions changing the cpu State and Machine

Implementations

impl Cpu

pub fn new() -> Cpu

Returns a Z80 Cpu instance. Alias of new_z80()

pub fn new_z80() -> Cpu

Returns a Z80 Cpu instance

pub fn new_8080() -> Cpu

Returns an Intel 8080 Cpu instance

impl Cpu

pub fn execute_instruction(&mut self, sys: &mut dyn Machine)

Executes a single instruction

Arguments

• sys - A representation of the emulated machine that has the Machine trait

pub fn disasm_instruction(&mut self, sys: &mut dyn Machine) -> String

Returns the instruction in PC disassembled. PC is advanced.

Arguments

• sys - A representation of the emulated machine that has the Machine trait

pub fn set_trace(&mut self, trace: bool)

Activates or deactivates traces of the instruction executed and the state of the registers.

Arguments

• trace - A bool defining the trace state to set

pub fn registers(&mut self) -> &mut Registers

Returns a Registers struct to read and write on the Z80 registers

pub fn immutable_registers(&self) -> &Registers

Returns an immutable references to Registers struct to read the Z80 registers

pub fn is_halted(&self) -> bool

Returns if the Cpu has executed a HALT

pub fn signal_interrupt(&mut self, active: bool)

Maskable interrupt request. It stays signaled until is is deactivated by calling signal_interrupt(false).

pub fn signal_nmi(&mut self)

Non maskable interrupt request

pub fn signal_reset(&mut self)

Signal reset

pub fn cycle_count(&self) -> u64

Returns the current cycle count

Trait Implementations

impl Default for Cpu

fn default() -> Self

Returns the “default value” for a type.
