## Overview

`dmacu` is an emulator for a simple hypothetical RISC-like processor intended to run on an ARM platform including a PL080 DMA controller.

The `dmacu` emulator itself executes on a DMA channel of the host system's PL080 DMA controller. Interaction from the host system's ARM core

is only needed to configure and start the DMA channel on which `dmacu` executes. No further interaction is needed from the host system's ARM

core once the DMA channel is up and running. The `dmacu` emulator remains operational while the host system's ARM core is in an active sleep

state (WFI/WFE), or while the ARM core is halted via an external debug interface.
