Analog Devices EE-148 Introduction to SHARC Multiprocessor Systems Using VisualDSP++

About this manual

This Engineer-to-Engineer note provides an introduction to configuring SHARC DSP multiprocessor systems using the VisualDSP++ 3.0 development environment. The document specifically uses two ADSP-21160 EZ-Kit boards as a code example to demonstrate system setup. It covers various configuration methods, including DSPs sharing the external bus, link port communication, and serial port multi-channel mode.

Frequently asked questions

What is the minimum number of processors required in a DSP multiprocessor system?

A DSP with ID=001 must be present in the system to drive the external bus control lines stable during reset.

What is the maximum number of ADSP-21160 processors that can be declared in one LDF?

The maximum number of processors that can be declared in one LDF is 6 for the ADSP-21160.

What address range corresponds to accessing the internal memory of a DSP with ID 3?

Accessing a memory location within the address range 0x300000 – 0x3FFFFF is equivalent to accessing the internal memory of the DSP with ID 3.
