SEMICONDUCTOR DEVICE

摘要

A semiconductor device includes a hash generator, a reference hash list, a frame mode determination unit, and an intra prediction unit. The hash generator generates a hash value of a target frame to be encoded. The reference hash list is to record the hash value generated by the hash generator. The frame mode determination unit compares the hash value generated by the hash generator and the hash value in the reference hash list. The intra prediction unit performs intra prediction for the target frame to be encoded. When the hash value of the target frame to be encoded coincides with any of the hash values in the reference hash list, the intra prediction unit skips an encoding process, and outputs encoded information corresponding to any of the hash values in the reference hash list.

1. A semiconductor device comprising:
a hash generator which generates a hash value of a target frame to be encoded; a reference hash list for recording the hash value generated by the hash generator; a frame mode generation unit which compares the hash value generated by the hash generator with any of hash values in the reference hash list; and an intra prediction unit which performs intra-frame prediction for the target frame to be encoded, wherein, when the hash value of the target frame to be encoded coincides with any of the hash values in the reference hash list, the intra prediction unit skips an encoding process, and outputs encoded information corresponding to any of the hash values in the reference hash list.
