摘要：
A processing system includes a cache, a host memory, a CPU and a hardware accelerator. The CPU accesses the cache and the host memory and generates at least one instruction. The hardware accelerator operates in a non-temporal access mode or a temporal access mode according to the access behavior of the instruction. The hardware accelerator accesses the host memory through an accelerator interface when the hardware accelerator operates in the non-temporal access mode, and accesses the cache through the accelerator interface when the hardware accelerator operates in the temporal access mode.
