Abstract: Aspects of the disclosure provide a method for merging compressed access units according to compression rates and/or positions of the respective compressed access units. The method can include receiving a sequence of compressed access units corresponding to a sequence of raw access units partitioned from an image or a video frame and corresponding to a sequence of memory spaces in a frame buffer, determining a merged access unit including at least two consecutive compressed access units based on compression rates and/or positions of the sequence of compressed access units. The merged access unit is to be stored in the frame buffer with a reduced gap between the at least two consecutive compressed access units compared with storing the at least two consecutive compressed access units in corresponding memory spaces in the sequence of memory spaces.

Abstract: A Graphics Processing Unit (GPU) concurrently executes kernel codes programmed in more than one programming framework. The GPU includes a first command decoder that decodes a first set of commands issued by a first Application Programming Interface (API) for executing a first kernel code. The GPU also includes a second command decoder that decodes a second set of commands issued by a second API for executing a second kernel code. The GPU also includes a plurality of shader cores and a pipe manager. According to decoded commands, the pipe manager assigns a first set of shader cores and a second set of shader cores to concurrently execute the first kernel code and the second kernel code, respectively.
