  • Patent number: 11294716
    Abstract: A processing system includes at least one core, at least one accelerator function unit (AFU) and an acceleration interface. The unit runs a plurality of processes and develops at least one task queue corresponding to each of the processes. The core generates several command packets and pushes them into the corresponding task queue. The AFU are used to execute the command packets. The acceleration interface is arranged between the AFU and the core to receive an acceleration interface instruction from the processing core, and establish a bit map based on the acceleration interface instruction. The bit map is used to indicate which task queue contains the command packets that have been generated.

  • Patent number: 9985648
    Abstract: The invention introduces a method for accelerating compression, performed in a compression accelerator, including: repeatedly executing a loop for determining the longest matched-length between a first string and a second string. Each iteration of the loop includes: obtaining n successive characters from the first string as a source string, wherein n is greater than 1; comparing each character of the source string with all characters of the second string, so as to generate n first-match-results corresponding to the n successive characters of the source string respectively; generating a second-match-result according to the n first-match-results; and determining whether a continuous match of the n successive characters is presented according to the second-match-result. If so, n is added to the matched length and the next iteration of the loop is continued to execute. Otherwise, a matched length is updated and output and the loop is exited.
