Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to implement predictor prefetching in video encoding. The example apparatus includes processor circuitry to perform operations to instantiate a predictor list generator circuitry and a predictor prefetch circuitry. The example predictor list generator circuitry to obtain predictor candidates indicating memory locations storing reference blocks from a previous block and sort the predictor candidates in a priority order. The example predictor prefetch circuitry to send cache line requests to the memory corresponding to at least some the predictor candidates that satisfy a threshold priority value. The example predictor prefetch circuitry to send the cache line requests to the memory before a reference block winner of the previous block is determined.
