This document is a technical note on using Analog Devices' DSP components and development tools, specifically focusing on the ADSP-21161N SHARC® DSP chip and its on-chip SDRAM controller. It provides information on the internal signal chain, address-mapping scheme, command truth table, power up sequence, code execution, and timing overview for different access modes. The on-chip SDRAM controller is a hardware intensive solution for addressing SDRAM with a DSP.
