Abstract: A system includes a processing unit such as a GPU that itself includes a command processor configured to receive instructions for execution from a software application. A processor pipeline coupled to the processing unit includes a set of parallel processing units for executing the instructions in sets. A set manager is coupled to one or more of the processor pipeline and the command processor. The set manager includes at least one table for storing a set start time, a set end time, and a set execution time. The set manager determines an execution time for one or more sets of instructions of a first window of sets of instructions submitted to the processor pipeline. Based on the execution time of the one or more sets of instructions, a set limit is determined and applied to one or more sets of instructions of a second window subsequent to the first window.

Abstract: A method of packet attribute confirmation includes receiving, at a command processor of a parallel processor, a command packet including a received packet attribute, such as a packet size, of the command packet. The command processor compares the received packet attribute of the command packet relative to an expected packet attribute of the command packet. The command processor passes one or more commands to a prefetch parser such that a summed total size of the one or more commands is equal to the received packet size of the command packet. The command processor passes, based at least on determining a match between the received packet size and the expected packet size, the received command packet to the prefetch parser. Otherwise, the command processor passes, based at least on determining a mismatch between the received packet size and the expected packet size, one or more no-operation instructions to the prefetch parser.
