US Patent 11620246 Enhanced peripheral processing system to optimize power consumption

A microcontroller system that includes a central processing unit (CPU), a first system memory, a first peripheral module, and a DMA controller is disclosed. The DMA controller includes a DMA processor, a DMA memory, and a DMA interconnect. The DMA memory stores information associated with the DMA processor. The DMA processor receives a command from the CPU or a signal from a peripheral processor of the first peripheral module that a first data transfer is requested. The DMA processor receives first data from the first system memory or the first peripheral module. The DMA processor, based at least in part on the information stored in the DMA memory, transmits the first data to the first peripheral module or the first system memory, thereby sparing the CPU from managing the transferring of the first data.
