Struct i8080::Intel8080

pub struct Intel8080 {
    pub cpu: Cpu,
    pub memory: Memory,
}

An Intel 8080 system.

Fields

cpu: Cpu

An Intel 8080 CPU.

memory: Memory

A 64K memory.

Implementations

impl Intel8080

pub fn new<P: AsRef<Path>>(paths: &[P], start_address: u16) -> Result<Self>

Creates an Intel 8080 system by loading ROM files located at paths into memory starting at start_address and setting the program counter to start_address.

Errors

This function will return an error (Error::FileNotFound, Error::Io, or Error::TooLargeFile) if a ROM file in paths cannot be read successfully or the total size of the ROM files is too large to be loaded into memory starting at start_address.

pub fn fetch_execute_instruction(&mut self) -> Result<(Instruction, u32)>

Fetches and executes an instruction, returning it with the number of states taken.

Errors

This function will return an Error::Halted error if the CPU is in the halted state.

pub fn interrupt(&mut self, instruction: Instruction) -> Result<u32>

Escapes from the halt state, if necessary, and executes instruction with further interrupts disabled.

Errors

This function will return an Error::InterruptNotEnabled error if the interrupt system is already disabled.
