ABSTRACT:
Presented herein are Tertiary Content Addressable Memory based motion estimator(s). In one embodiment, there is presented a method for encoding a picture. The method comprises storing a reference picture in a memory; taking samples from at least one line of a prediction block, wherein each of the samples comprises a plurality of bits, the plurality of bits comprising most significant bits and least significant bits; concatenating the samples; replacing the least significant bits of the samples with “don't cares”, thereby generating at least one data word; addressing the memory with the at least one data word; receiving one or more addresses, said one or more addresses associated with one or more blocks; replacing a portion of the “don't cares” with a portion of the least significant bits of the samples, thereby generating another one or more data words; and addressing the memory with the another one or more data words.
