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.
