This document provides technical notes on using Analog Devices' DSP components and development tools. Specifically, it describes how to use the IO space of the ADSP-2181 DSP to boot another ADSP-2181 using the IDMA port. The host DSP can access the target ADSP-2181's internal memory through the IDMA port. The target DSP is treated as a memory mapped slave peripheral, allowing the host processor to access its internal data memory and program memory, excluding control registers.
