2results about How to "Maximize Bandwidth Utilization" patented technology

This invention discloses a graphics processing unit (GPU), a task execution method, an electronic device, and a storage medium. The GPU includes at least a filtering calculation unit, an execution unit, a first data loading unit, and a second data loading unit. The first data loading unit loads execution data for a first filtering task and stores the execution data in a first buffer. The second data loading unit loads execution data for a second filtering task and stores the execution data in a second buffer. The execution unit filters target execution data that meets the full-load condition of the filtering calculation unit from the first and second buffers and transmits the target execution data to the filtering calculation unit. The filtering calculation unit performs filtering calculations on the target execution data. This invention maximizes the bandwidth utilization of the filtering calculation unit and improves the execution efficiency of the GPU's filtering tasks.

This invention discloses a SATA command acceleration system and method. The system includes a command queue, a DMA queue, a submission unit, a hardware resource management unit, and a DMA status queue, used to record the status of DMA tasks completed by the DMA engine. The firmware periodically processes commands in the command queue to configure corresponding DMA task descriptors in the DMA queue, and periodically queries the DMA status queue to determine the completion status of SATA commands. Thus, through hardware-coordinated management of the command, DMA, and status queues, the system reduces the real-time DMA transfer management task of the firmware, achieving automation and pipelined DMA transfer, thereby significantly reducing CPU load and improving data transfer efficiency and system response speed. It reduces firmware intervention in the SATA command transfer process, lowering CPU load; and through queuing and automation mechanisms, it achieves seamless DMA transfer, maximizing bus bandwidth utilization.
