Analog Devices ADSP-219x/2191 DSP Hardware Reference Manual
This manual serves as a comprehensive hardware reference for engineers working with the ADSP-219x/2191 DSP family. It is intended for hardware designers, firmware developers, and system integrators who need in‑depth knowledge of the processor's architecture and operation.
The document covers the core DSP architecture, memory organization, interrupt handling, DMA controller, and peripheral interfaces such as SPORT, SPI, UART, and the host port. It also describes computational units, boot modes, low‑power operation, and JTAG debugging features, providing register‑level details and usage examples.

Questions answered in these manuals
What is the purpose of a software overlay system?
It allows an application to exceed internal memory limits by fetching code or data from external memory into the DSP's internal memory at runtime.
From: Analog Devices ADSP-219x Using Software Overlays with VisualDSP 2.0 Application Note
How many overlays can map to a single runtime location?
Multiple overlays can share the same internal memory segment; for example, three program memory overlays can map to one run space.
From: Analog Devices ADSP-219x Using Software Overlays with VisualDSP 2.0 Application Note
How many instructions can be in different stages of completion?
During any given cycle, up to 6 instructions may be in different stages of completion.
From: Analog Devices ADSP-219x Pipeline Overview Technical Note
What is the latency for servicing an interrupt?
There is a minimum pipeline latency of 4-cycles in servicing an interrupt.
