Abstract: A sliced graphics processing unit (GPU) architecture in processor-based devices is disclosed. In some aspects, a GPU based on a sliced GPU architecture includes multiple hardware slices. The GPU further includes a command processor (CP) circuit and an unslice primitive controller (PC_US). Upon receiving a graphics instruction from a central processing unit (CPU), the CP circuit determines a graphics workload, and transmits the graphics workload to the PC_US.
