Struct acs::arch::screen::Screen

pub struct Screen { /* private fields */ }

512x256 black-and-white screen which behaves like a Ram8k.

Implementations

impl Screen

pub fn sim(&mut self, inp: Signal16, load: Signal, address: Signal13) -> Signal16

Carries out the simulation, taking as input:

• inp: data input
• load: whether to write inp into the RAM
• address: which register to select

It returns the value stored at address. Furthermore, when load is HI, inp is written at location address, and the loaded value will be emitted from the next time step onward.

The pixel at row r from the top and column c from the left, is mapped onto the c % 16 bit (from LSB to MSB) of the 16-bit word stored at address r * 32 + c / 16.

pub fn dump(&self, path: impl AsRef<Path>) -> Result<(), Box<dyn Error>>

Trait Implementations

impl Default for Screen

fn default() -> Self

Returns the “default value” for a type.

impl Unit for Screen

fn tick(&mut self)

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

fn eval(&mut self)

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

fn tock(&mut self)

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