1.2 Characteristics
The M65727 has the following characteristics.
*Highly efficient parallel architecture for high speed processing and data transfer, which
eliminates I/O bottleneck.
*Supports prediction modes for MPEG2, Field prediction, Frame prediction, Field Dual-Prime
prediction and Frame Dual-Prime prediction.
*For Field Mode and Frame Mode, it is possible to do simultaneous vector search over 16x16 and two
16x8 blocks.
*Implementing low cost image compression hardware is possible using DRAM frame memory in a 32
bit DRAM interface.
*Estimates half-pel precision vectors in a chip.
*The exhaustive search method is used over the integer-pel precision vectors in a search range.
Evaluation function is full sampled mean absolute error.
*The M65727's scalable architecture allows wider search range with multiple-chip configuration.
When expanding the horizontal search range, it is possible to use a common search window image
data into all chips.
