Abstract: Techniques are described for determining whether execution of an instruction would require reading more values from a memory cell of a general purpose register (GPR) than a read port of the memory cell would allow. In such a case, the techniques may store, prior to execution of the instruction, one or more values from the memory cell in a separate conflict queue. During execution of the instruction to implement an operation defined by the instruction, one value that is an operand of the operation would be read from the memory cell and another value that is an operand of the operation other would be read from the conflict queue.

Abstract: Methods, systems, and devices for image processing are described. A device may determine, based on a test operation, to terminate a first wave associated with a first slot of a set of slots. The device may update a terminated wave bit associated with the first slot based on the determination to terminate the first wave. In some aspects, the device may update a number of invocations field associated with the first wave based on the determination to terminate the first wave. The device may release the first slot based on updating the terminated wave bit and the number of invocations field. In some examples, the device may output the number of invocations field to a rendering backend of the device based on the terminated wave bit.

Abstract: This disclosure provides systems, devices, apparatus and methods, including computer programs encoded on storage media, for GPR optimization in a GPU based on a GPR release mechanism. More specifically, a GPU may determine at least one unutilized branch within an executable shader based on constants defined for the executable shader. Based on the at least one unutilized branch, the GPU may further determine a number of GPRs that can be deallocated from previously allocated GPRs. The GPU may deallocate, for a subsequent thread within a draw call, the number of GPRs from the previously allocated GPRs during execution of the executable shader based on the determined number of GPRs to be deallocated.
