Coding tools
— High-performance motion estimation
— All variable block sizes are supported (in case of encoding, 8 × 4, 4 × 8, and 4 × 4 block sizes
— 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
— CIR (Cyclic Intra Refresh)/AIR (Adaptive Intra Refresh)
— Error resilience tools
— 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
— Embeds 16-bit DSP processor that is dedicated to processing bitstream and driving codec
— General purpose registers and interrupt generation for communication between system and
Signal Descriptions
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.
Programmability
– 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
