Abstract: A processing system has a keyword recognition sub-system and a direct memory access (DMA) controller. The keyword recognition sub-system has a processor and a local memory device. The processor performs at least keyword recognition. The local memory device is accessible to the processor and is arranged to buffer at least data needed by the keyword recognition. The DMA controller interfaces between the local memory device of the keyword recognition sub-system and an external memory device, and is arranged to perform DMA data transaction between the local memory device and the external memory device.
