A Direct Memory Access Controller (DMAC) IP-Core using the AMBA AXI protocol

Ilan CorreaJosé Luís GüntzelAldebaro KlautauJoão Crisóstomo Costa

This work presents the design of a hardware controller that allows a peripheral of an embedded computer system to directly access the memory, known as direct memory access controller (DMAC). This DMAC is inspired in the Dalton Project DMAC, also being compatible with the widely used Intel I8237. In order to make it suitable for current embedded applications, its communication pattern follows the AMBA AXI protocol, which allows more flexibility such as fewer timing restrictions and data transfer in the system with minimum CPU load.
