Abstract: A graphics processing unit (GPU) utilizes block general purpose registers (bGPRs) to load multiple waves of samples for an instruction group into a processing pipeline and receive processed samples from the pipeline. The GPU acquires a credit for the bGPR for execution of the instruction group for a first wave using a persistent GPR and the bGPR. The GPU refunds the credit upon loading the first wave into the pipeline. The GPU executes a subsequent wave for the instruction group to load samples to the pipeline when at least one credit is available and the pipeline is processing the first wave. The GPU stores an indication of each wave that has been loaded into the pipeline in a queue. The GPU returns samples for a next wave in the queue from the pipeline to the bGPR for further processing when the physical slot of the bGPR is available.

Abstract: An isolated resonant converter has an analog comparator with hysteresis for generating a first ON/OFF signal, a digital isolator for outputting a second ON/OFF signal, an oscillator for providing a clock pulse signal with a frequency, and a primary pulse width modulator coupled to receive the clock pulse signal and the second ON/OFF signal. An output voltage of the isolated resonant converter is controlled by the analog comparator within a predefined range. The second ON/OFF signal is electrically isolated from the first ON/OFF signal. The primary pulse width modulator controls the switching of the isolated resonant converter in response to the clock pulse signal during the logic high state of the second ON/OFF signal and stops the switching of the isolated resonant converter during the logic low state of the second ON/OFF signal.
