DMA + CLIB
In our trust engine, we use a DMA engine with a crypto lib to do authentication/encr/decr work, this article introduces the whole structure of this DMA + CLIB structure and summarize all transfer patterns.
AXI procol
In this article, we will introduce the AXI protocol which is a high performance, high bandwidth, low latency interconnect for high speed communication between components on the same chip. The AXI protocol is based on a point-to-point interconnect to provide high-speed data transfer between the master and slave components. The AXI protocol is designed to support multiple masters and multiple slaves, and it is widely used in many modern SoC designs.
