DMA Controller *
DMA stands for Direct Memory Access. DMA provides a way for devices to transfer information directly to and from memory, without the processor's intervention

GDA's DMA Controller core is highly configurable and structured design to suit the requirement of the designers.

The core is provided with the generic processor bus interface on the system side enabling the core to be used in a variety of applications including SoC applications. The core's simple and configurable architecture is independent of implementation tools and, most importantly, target technologies. GDA's DMA Controller core is a cost-effective, end-to-end solution that allows the licensees to easily migrate to FPGA, Gate array and Standard cell technologies optimally.
