Expand description

A helper trait for accessing parameters of well-known host configurations.

Required Associated Constants§

source

const CPU_HZ: u32

The number of CPU cycles (T-states) per second.

source

const FRAME_TSTATES: FTs

The number of CPU cycles (T-states) in a single execution frame.

Provided Methods§

source

fn effective_cpu_rate(multiplier: f64) -> f64

Returns the CPU rate (T-states / second) after multiplying it by the multiplier.
