Struct acs::arch::computer::Computer

pub struct Computer { /* private fields */ }

The computer consists of three parts:

• Central Processing Unit (CPU)
• Memory (RAM)
• Instruction Memory (ROM)

This configuration with two separate address space for instructions and data is called Hardware architecture.

The intruction memory out signal is feed to the instruction input of the CPU, which is then executed. This execution may involve reading or writing data to memory registers. The CPU also figures out the instruction to fetch next and emits this address through its pc output. The pc output is feed to the address input of the instruction memory.

Implementations

impl Computer

pub fn set_instructions(&mut self, instructions: Vec<AsmInstruction>)

Loads instructions into the ROM

pub fn reset(&mut self)

pub fn get_screen(&self) -> &Screen

pub fn get_keyboard_mut(&mut self) -> &mut Keyboard

pub fn get_memory(&self) -> &Memory

pub fn get_memory_mut(&mut self) -> &mut Memory

pub fn ticktock(&mut self)

Advances one cicle

Trait Implementations

impl Default for Computer

fn default() -> Computer

Returns the “default value” for a type.

impl Unit for Computer

fn tick(&mut self)

Carries out the tick-phase of a clock cycle: LOW

fn tock(&mut self)

Carries out the tock-phase of a clock cycle: HIGH

fn eval(&mut self)

Evaluates the logic expression as we do with arithmetic without advancing the time.
