Abstract
A processing and storage circuit includes an internal bus, one or more first-level internal memory units, a central processing unit (CPU), one or more hardware acceleration engines, and an arbiter. The first-level internal memory unit is coupled to the internal bus. The CPU includes a second-level internal memory unit, and is configured to access the first-level internal memory unit via the internal bus, and when the CPU accesses data, the first-level internal memory unit is accessed preferentially. The hardware acceleration engine is configured to access the first-level internal memory unit via the internal bus. The arbiter is coupled to the internal bus, configured to decide whether the CPU or the hardware acceleration engine be allowed to access the first-level internal memory unit. The arbiter sets the priority of the CPU accessing the first-level internal memory unit to be over the hardware acceleration engine.
