Abstract
Mechanisms for reducing register bank conflicts based on software hint and hardware thread switch are disclosed. In some embodiments, an apparatus for thread switching includes a graphics processing unit (GPU) that includes a plurality of register banks to store operands that are assigned at least partially to avoid register bank conflicts. Decoding circuitry checks a thread switching field of a first instruction to be executed by a first thread. The GPU performs a thread switch mechanism to cause a second instruction to be executed by a second thread when the thread switching field of the first instruction is set.
