∙Chapter 6 - Use of the DMA Resource, develops guidelines and rules for creating eXpressDSP-compliant algorithms that utilize the DMA resource.

∙Appendix A - Rules and Guidelines, contains a complete list of all rules and guidelines in this specification.

∙Appendix B - Core Run-time Support APIs, contains a complete description of the APIs that an eXpressDSP-compliant algorithm may reference.

Related Documentation

The TMS320 DSP Algorithm Standard is documented in the following manuals:

∙TMS320 DSP Algorithm Standard Rules and Guidelines (this document). Describes all the rules and guidelines that make up the TMS320 DSP Algorithm Standard (may be referred to as XDAIS throughout this document).

∙TMS320 DSP Algorithm Standard API Reference (SPRU360). Contains APIs that are required by the TMS320 DSP Algorithm Standard and full source examples of eXpressDSP-compliant algorithm components.

∙TMS320 DSP Algorithm Standard Developer's Guide (SPRU424). Contains examples that assist the developer in implementing the XDAIS interface and to create a test application.

∙Using DMA with Framework Components for C64x+ Application Report (SPRAAG1). Describes the standard DMA software abstractions and interfaces for TMS320 DSP Algorithm Standard (XDAIS) compliant algorithms designed for the C64x+ EDMA3 controller using DMA Framework Components utilities.

Although these documents are largely self-contained, there are times when it is best not to duplicate documentation that exists in other documents. The following documents contain supplementary information necessary to adhere to the TMS320 DSP Algorithm Standards.
