Coding tools
— High-performance motion estimation
– Single reference frame for both MPEG-4 and H.264 encoding
– Support 16 reference frame for H.264 decoding
– Quarter-pel and half-pel accuracy motion estimation
– [+/-16, +/-16] Search range
– Unrestricted motion vector
— All variable block sizes are supported (in case of encoding, 8
×
4, 4
×
8, and 4
×
4 block sizes
are not supported).
— MPEG-4 AC/DC prediction and H.264 Intra prediction
— H.263 Annex I, J, K(RS = 0 and ASO =0), and T are supported. In case of encoding, the Annex
I and K(RS=1 or ASO=1) are not supported.
— CIR (Cyclic Intra Refresh)/AIR (Adaptive Intra Refresh)
— Error resilience tools
– MPEG-4 re-synchronize marker and data-partitioning with RVLC (fixed number of
bits/macroblocks between macroblocks)
– H.264/AVC FMO and ASO
– H.263 slice structured mode
— Bit-rate control (CBR and VBR)
Pre/post rotation/mirroring
— 8 rotation/mirroring modes for image to be encoded
— 8 rotation/mirroring modes for image to be displayed
Programmability
— Embeds 16-bit DSP processor that is dedicated to processing bitstream and driving codec
hardware
— General purpose registers and interrupt generation for communication between system and
video codec module

Signal Descriptions
This section discusses the following:
Identifies and defines all device signals in text, tables, and (as appropriate) figures. Signals can be
organized by group, as applicable.
Contains pin-assignment/contact-connection diagrams, if the sequence of information in the data
sheet requires them to be included here.
