  • Publication number: 20240078630
    Abstract: Embodiments described herein are generally directed to improvements relating to power, latency, bandwidth and/or performance issues relating to GPU processing/caching. According to one embodiment, a system includes a producer intellectual property (IP) (e.g., a media IP), a compute core (e.g., a GPU or an AI-specific core of the GPU), a streaming buffer logically interposed between the producer IP and the compute core. The producer IP is operable to consume data from memory and output results to the streaming buffer. The compute core is operable to perform AI inference processing based on data consumed from the streaming buffer and output AI inference processing results to the memory.

  • Publication number: 20230306551
    Abstract: Described herein is a graphics processor comprising a processing resource configured to perform processing operations, a codec configured to compress and decompress data associated with the processing operations, and circuitry configured to calculate a metadata address for a compressed surface based on a flat virtual memory address mapping between the address of the compressed surface and the metadata address. The compressed surface is to store data associated with a processing operation to be performed by the processing resource and the metadata address is a virtual address that stores compression metadata for the compressed surface. The circuitry can configure the codec to access the compressed surface based on the compression metadata.

  • Publication number: 20230260075
    Abstract: Embodiments described herein are generally directed to improvements relating to power, latency, bandwidth and/or performance issues relating to GPU processing/caching. According to one embodiment, a state of multiple intellectual property (IP) cores that have access to a common cache via a central fabric is observed. Responsive to the observed state being indicative of performance of a standalone workload by a first IP core of the multiple IP cores, the common cache is treated as a local cache of the first IP core by powering off the central fabric and causing the first IP core to access the common cache via a low power access path between the first IP core and the common cache that is outside of the central fabric.
