Optimize SoC Design
The Direct Memory Access (DMA) controller enables the movement of blocks of data from peripheral to memory, memory to peripheral, or memory to memory without burdening the processor.
The DMA-230 is a low gate count (3-10k gates) micro-DMA engine targeting Cortex-M3 systems and other low-power and cost-sensitive applications. The device offers excellent performance at low gate count and all the code is stored in system RAM rather than in registers. Using this component enables Cortex-M1 and Cortex-M3 based systems to remain low cost through reduced gate count and enabling scaling down the frequency of the processor in the system for reducing overall power consumption.
Efficient use of DMA can significantly improve system performance in multiple dimensions. For example, using a DMA controller can offload a processor and either reduce power consumption, or boost the processor performance, or a combination of both.
AMBA DMA controllers provide a centralized DMA processing capability that is high performance and highly flexible, and at the same time, is area efficient.
