Field Dual-Prime Mode

*Block size

16x16

*Search range

Second field: horizontal ±0.5 pixel, vertical: ±0.5 pixel

*Search method Take the average with the first field data (half-pel is generated as needed)

and estimate 9 points over the second field (including the specified point)

*Evaluation function Full sampled mean absolute error

*Execution cycle The execution cycle mentioned here refers to the throw-in period of MB,

not the 1MB processing time. (550) cycles / MB

*Search window image inputs

First field: 432 (18x24) pixel / (550) cycles

Second field: 432 (18x24) pixel / (550) cycles

*Processing capability

27MHz operation: Processing the search range over horizontal ±7.5 and

vertical ±7.5 for the ITU-R 601 image size is possible.

Frame Dual Prime Mode

*Block size

16x8

*Search range

Second field: horizontal ±0.5 pixel, vertical: ±0.5 pixel

*Search method Take the average with the first field data (half-pel is generated as needed)

and estimate 9 points over the second field (including the specified point)

Not only the minimum evaluation value, but also all the 9 points are stored

and output.

*Execution cycle The execution cycle mentioned here refers to the throw-in period of MB,

not the 1MB processing time. (550) cycles / MB

*Search window image inputs

First field: 288 (18x16) pixel / (550) cycles

Second field: 288 (18x16) pixel / (550) cycles

*Processing capability

27MHz operation: Processing the search range over horizontal ±7.5 and

vertical ±7.5 for the ITU-R 601 image size is possible.

***: The Frame Dual-Prime Mode supports a part of Dual-Prime prediction specified

by the MPEG2.
