This application note 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. The DMA Framework Component utilities described in this document include a standard DMA resource specification and negotiation protocol (IDMA3), a DMA Resource Manager (DMAN3), and a functional DMA interface and library (ACPY3) compliant with IDMA3. This document provides both reference information and guidelines for producers and consumers of IDMA3-compliant algorithms and components.
