  • Publication number: 20240289276
    Abstract: A uniform cache for fast data access including a plurality of compute units (CUs) and a plurality of LO caches with an arrangement in a network configuration where each one of CUs is surrounded by a first group of the plurality of LO caches and each of the plurality of LO caches is surrounded by a LO cache group and CU group. One of CUs, upon a request for data, queries the surrounding first group of LO caches to satisfy the request. If the first group of LO caches fails to satisfy the data request, the first group of the plurality of LO caches queries a second group of adjacent LO caches to satisfy the request. If the second group of adjacent LO caches fails to satisfy the data request, the second group of adjacent LO caches propagating the query to the next group of LO caches.

  • Patent number: 12001334
    Abstract: A uniform cache for fast data access including a plurality of compute units (CUs) and a plurality of L0 caches with an arrangement in a network configuration where each one of CUs is surrounded by a first group of the plurality of L0 caches and each of the plurality of L0 caches is surrounded by a L0 cache group and CU group. One of CUs, upon a request for data, queries the surrounding first group of L0 caches to satisfy the request. If the first group of L0 caches fails to satisfy the data request, the first group of the plurality of L0 caches queries a second group of adjacent LO caches to satisfy the request. If the second group of adjacent L0 caches fails to satisfy the data request, the second group of adjacent L0 caches propagating the query to the next group of L0 caches.

  • Publication number: 20220188232
    Abstract: A uniform cache system and method for fast data access are disclosed. The system and method include a plurality of compute units (CUs) and a plurality of L0 caches. The plurality of CUs and the plurality of L0 caches are arranged in a network configuration where each one of the plurality of CUs is surrounded by a first group of the plurality of L0 caches and each of the plurality of L0 caches is surrounded by a L0 cache group and CU group. Operationally, ones of the plurality of CUs, upon a request for data, queries the surrounding first group of the plurality of L0 caches to satisfy the request. On a condition that the first group of the plurality of L0 caches fails to satisfy the data request, each of the first group of the plurality of L0 caches query a second group of adjacent L0 caches to satisfy the request. On a condition that the second group of adjacent L0 caches fails to satisfy the data request, each of the second group of adjacent L0 caches propagating the query to the next group of L0 caches.

  • Patent number: 10805622
    Abstract: Aspects of the present disclosure provide a method and an apparatus for video coding. In some examples, the apparatus includes processing circuitry that divides a first video image into a plurality of pixel blocks of the same size. The processing circuitry selects, from the plurality of pixel blocks of the first video image, one or more pixel blocks on a straight line that is parallel to or overlapping with a diagonal line of the first video image, one or more pixel blocks on a neighboring parallel line of the straight line being previously coded. Then the processing circuitry performs a parallel coding on the one or more pixel blocks on the straight line based on the one or more coded pixel block on the neighboring parallel line.
