Abstract: Systems, methods, and computer programs are disclosed for reducing memory bandwidth via multiview compression/decompression. One embodiment is a compression method for a multiview rendering in a graphics pipeline. The method comprises receiving a first image and a second image for a multiview rendering. A difference is calculated between the first and second images. The method compresses the first image and the difference between the first and second images. The compressed first image and the compressed difference are stored in a memory. The compressed first image and the compressed difference are decompressed. The second image is generated by comparing the first image to the difference.

Abstract: Systems, methods, and computer programs are disclosed for controlling memory frequency. One method comprises a first memory client generating a compressed data buffer and compression statistics related to the compressed data buffer. The compressed data buffer and the compression statistics are stored in a memory device. Based on the stored compression statistics, a frequency or voltage setting of the memory device is adjusted for enabling a second memory client to read the compressed data buffer.
