Overview
The DMA controller is designed for data transfer in different system environments. Two module types : type 0 and type 1 are provided, and the user can choose the number of each module type. Type 0 modules are designed to transfer data residing on the same bus, and Type 1 modules are designed to transfer data between two different buses. Each module can support up to 4 DMA channels and the IP supports up to 16 total DMA channels. Each DMA channel can be programmed for various features, such as transfer size, synchronized and unsynchronized transfer control, transfer priority, interrupt generation, memory and I/O address space, and address change direction. This IP is designed to work with 32-bit and 64-bit bus systems, including the PCI bus, PowerPC bus, and other CPU host buses. It can also be integrated with other IP to form a complete functional block.
