  • Publication number: 20130028324
    Abstract: A method and device for decoding a scalable video signal utilizing an inter-layer prediction are provided herein. An inter-layer pre-fetch scheme (IPS) is presented to improve the performance for scalable video coding (SVC) decoder. With proposed invention, the required information for inter-layer prediction in SVC technique will be pre-fetched ahead when reconstructing the enhancement layer so that the cache miss rate can be reduced significantly. Accordingly, the execution time and memory energy consumptions can be improved.

  • Publication number: 20130031327
    Abstract: Different processor elements in multi-task/multi-core system on chip may have different memory requirements at runtime. The method for adaptively allocating cache memory re-allocates the cache resource by updating the bank assignment table. According to the associativity-based partitioning scheme, centralized memory is separated into several groups of SRAM banks which are numbered differently. These groups are assigned to different processor elements to be L2 caches. The bank assignment information is recoded in bank assignment table, and is updated by system profiling engine. By changing the information in bank assignment table, the cache resource re-allocation for processor elements is achieved.

  • Patent number: 7903443
    Abstract: The present invention discloses a butterfly match-line structure and a search method implemented thereby, wherein the parallelism of the match lines is increased to shorten the search time, and a butterfly-type connection is used to reduce the power consumption and achieve the best energy efficiency. Via the butterfly-type connection, information can be reciprocally transmitted between the parallel match lines, which are independent originally. When a miss case occurs, more succeeding memory cells will not be compared but will be turned off. Thereby, the power consumption is reduced. Further, XOR-based conditional keepers are used to reduce the matching time and the power consumption. Besides, such a circuit is also used to shorten the delay time of the butterfly-type connection.
