Abstract: A Streaming Wave Coalescer (SWC) circuit stores a first set of state values associated with a first subset of threads of a first wave in a bin based on each of the first subset of threads including a first set of instructions to be executed. A second set of state values associated with a second subset of threads of a second wave is stored in the bin based on each of the second subset of threads including the first set of instructions to be executed and based on the first wave and the second wave both being associated with a hard key. A third wave is formed from the threads of the first subset and the second subset and is emitted for execution. As a result of reorganizing the threads and reconstituting a different wave, thread divergence of waves sent for execution is reduced.
