Abstract

DMA transfer copies data from one address space to another, providing high-speed data transfer between peripherals and storage or between storage and storage. The DMA transmission method does not require the CPU to directly control the transmission, saving CPU resources and greatly improving CPU efficiency. With the rapid development of microcontrollers in the field of automotive electronics, microcontrollers that meet the requirements of automotive regulations should have high reliability and security. The application of AES encryption function in DMA can effectively improve security. This design is based on the AES encryption function and the DMA controller design for 16byte bursts. Compared to the DES algorithm, it reduces the time loss of 8ns by transmitting data every 10k bytes. AES encryption and decryption functions are added to the DMA transmission. The design for 16byte burst DMA transmission based on AES encryption is developed in Verilog, and the simulation verification is done.
