Consistency for Compressed Data Across Graphics Cores
This abstract first appeared for US patent application 20250103501 titled 'Consistency for Compressed Data Across Graphics Cores
Original Abstract Submitted
techniques are disclosed relating to data compression in graphics processors. in some embodiments, first and second graphics processor cores include respective shader processor circuitry configured to execute graphics shader programs. cache circuitry may be configured to store surface data, including a compressed block of surface data and metadata for the compressed block of surface data. lock control circuitry may lock metadata for the second graphics processor core for the compressed block of surface data based on an access to the metadata by the first graphics processor core and prevent read accesses to the compressed block by the second graphics processor core until the lock on the metadata is released. this may provide consistency across graphics cores for compressed data.
