GRDMAC2 is a flexible direct memory access controller with AHB or AXI4 interface. It can be configured to include hardware accelerators for AES-256 and SHA-256 functionalities.
GRDMAC2 is a flexible direct memory access controller with AHB or AXI4 interface. It can be configured to include hardware accelerators for AES-256 and SHA-256 functionalities.
GRDMAC2 can perform burst transfers of data between AHB and APB peripherals at aligned or unaligned memory addresses. GRDMAC2 can be instantiated with one or two DMA interfaces to perform transfers among different AHB buses, therefore GRDMAC2 has a bridging capability.
GRDMAC2 works with self contained descriptors, with all information needed for the DMA transaction. Descriptor configuration allows specification of source and destination addresses which allows scatter/gather behavior. GRDMAC2 allows multiple types of descriptors which can be broadly classified as data descriptor and conditional descriptor. This enables GRDMAC2 to perform regular datat ransfer as well as perform an action on occurrence of a specific condition. Conditional descriptors allows an if-else mode of execution based on the condition check outcome
