Abstract
A processing system includes at least one core, a plurality of accelerator function unit (AFU) and a memory access unit. The memory access unit includes at least one pipeline resource and an arbitrator. The core develops a plurality of tasks. Each of the AFU is used to execute at least one of the tasks which corresponds to several memory access requests. The arbitrator selects one of the AFUs using a round-robin method at each clock period to transmit a corresponding memory access request of the selected AFU to the pipeline resource, so that the selected AFU executes the memory access request through the pipeline resource to read or write data related to the task.
