Technical Overview of eXpressDSP-Compliant Algorithms for DSP Software Producers (Rev. C)

Advances in digital signal processor (DSP) technology in the application areas of telephony, imaging, video, and voice are often results of years of intensive research and development.

For example, algorithm standards for telephony have taken years to develop. The implementation of these DSP algorithms is often very different from one application system to another because systems have, for example, different memory management policies and I/O handling mechanisms. Because of the lack of consistent system integration or programming standards, it is not possible for a DSP implementation of an algorithm to be used in more than one system or application without significant reengineering, integration, and testing.

This document targets these algorithms and assists the reader with making the algorithms compliant with the TMS320 DSP Algorithm Standard which is part of TI's eXpressDSP™ technology initiative. Algorithms that comply with the standard are tested and awarded an eXpressDSP compliant mark upon successful completion of the test.

It is assumed that the reader of this document has read or is familiar with the specifications of the standard.
