Texas Instruments Codec Engine Server - Manual (Page 11)

Where Does the Codec Engine Fit into My Architecture?
Codec Engine Overview 1-5
The following figure is a modification of the previous diagram that shows
how this architecture is distributed in a GPP+DSP system. In this
example, yellow portions run on the GPP, and grey portions run on the
DSP. This is, the video encoder skeleton and the video encoder codecs
are on the DSP and the application and video encoder stubs are on the
GPP.
Since Codec Engine is flexible, alternate diagrams could be shown for
GPP-only and DSP-only systems.
