MAP-CA DSP MPEG-4 video decoder at a glance

The Equator Technologies, Inc. MAP-CA DSP MPEG-4 Decoder Media Library Reference Source
Code Software Package provides an example implementation of MPEG-4 video image decoding on the
MAP-CA digital signal processor. This software can be used by developers as a reference for creating
their own MPEG-4 decoders for the MAP-CA DSP.

Features

The MAP-CA DSP MPEG-4 video decoder provides a number of important features for software
developers:

implementation as a well-documented set of C source code modules that utilize MAP-CA DSP
Media Intrinsics C extensions

inclusion of highly optimized, re-usable software modules, designed to allow users of the
MAP-CA DSP to quickly adopt these modules to their own code base

examples of efficient and parallel use of resources on the MAP-CA DSP, including

DataStreamer DMA controller

VLx coprocessor

Media Intrinsics C extensions

data cache and instruction cache

Benefits

The MAP-CA DSP MPEG-4 video decoder provides easily adaptable software modules for software
developers. The benefits include

substantial savings in development costs

greatly improved time to market

Performance

The MAP-CA DSP MPEG-4 Decoder Media Library Reference Source Code is intended to provide a
basis for customer development of MPEG-4 decoder software, and has not yet been fully optimized for
performance, nor does it contain comprehensive error handling or other production-level code routines.
As such, it does not demonstrate the full potential performance of optimized code running on the
MAP-CA DSP.

The MAP-CA DSP is capable of decoding two Simple Profile at Simple Level (SP@SL) MPEG-4 video
streams in real time, with sufficient cycles left to perform other tasks, such as the audio and system
decoding.

Processor support

The MAP-CA DSP MPEG-4 Decoder Media Library Reference Source Code Software Package fully
supports the MAP-CA digital signal processor.

Development platform support

The MAP-CA DSP MPEG-4 Decoder Media Library Reference Source Code Software Package fully
supports the Shark series of evaluation and development platforms from Equator Technologies.

Functionality

The MAP-CA DSP MPEG-4 video decoder passes all MPEG-4 standard conformance streams. This
decoder supports 4:2:0 coded video format and Simple Profile at Simple Level (SP@SL) video streams.
The decoder performs DC prediction and AC prediction. The current version of this decoder does not
support error checking.
