Traits

ControlUnit

This trait provides the interface for running the emulation and accessing instances of peripheral devices.

EarIn

A trait for feeding the EAR line input.

FrameState

The trait for reading and modifying the state of frame and cycle counters.

HostConfig

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

InnerAccess

A generic trait, useful for chipset implementations based on other underlying implementations.

MemoryAccess

A trait for directly accessing an emulated memory implementation and memory extensions.

MicOut

A trait for reading the MIC line output.

UlaCommon

A grouping trait of all common control traits for all emulated Ula chipsets except audio rendering.

UlaControl

Specialized ULA functionality access methods.

Functions

duration_from_frame_tc_cpu_hz

Returns a duration from the number of T-states in a single frame and a CPU clock rate.

nanos_from_frame_tc_cpu_hz

Returns the number of nanoseconds from the number of T-states in a single frame and a CPU clock rate.
