Abstract
The disclosure describes wireless communication systems. The wireless communication system includes first memory, second memory, a direct memory access (DMA) controller, an encryption engine in-line between the DMA controller and the second memory, a first microprocessor, and a second microprocessor. The first microprocessor communicates with other systems that generate application data to be wirelessly transmitted. The application data to be wirelessly transmitted is stored in the second memory and programs the DMA controller to transfer packets of the application data to the first memory from the second memory. The encryption engine receives the packets of the application data from the DMA controller, encrypts the packets to generate encrypted application data packets, and outputs the encrypted application data packets for storage to the first memory.
