Video Decoder User Interface (VDEC) User Interface
The VDEC User interface is split into two interfaces.
• One that concerns Post Processor and is common to all Decoder Modes, described by Video Post Processor
Register Mapping.
• One in which registers and fields depend on the Decoder Mode used. For best readability this document
describes one Register Mapping for each Decoder Mode. The relations are given in
.
Note:
The decoder mode is defined by the field DEC_MODE in Decoder Control Register 0.
