摘要
Systems, apparatuses, and methods for compressing pixel data are disclosed. In one embodiment, if a block of pixel data is equal to a constant value, a processor compresses the block down to a metadata value which specifies the constant value for the entire block of pixel data. The processor also detects if the constant value is equal to a video specific typical minimum or maximum value. In another embodiment, the processor receives a plurality of M-bit pixel components which are most significant bit aligned in N-bit containers. Next, the processor shifts the M-bit pixel components down into least significant bit locations of the N-bit containers. Then, the processor converts the N-bit containers into M-bit containers. Next, the processor compresses the M-bit containers to create a compressed block of pixel data which is then stored in a memory subsystem.
