WebDMA is doing data movement without a processor (master) is involved and is usually needed when you need high throughput. A processor is not usually good at doing memory transfers. DMA is also usually using burst mode on the interconnect to further improve throughput. A DMA can only do single transfer although it will not be very effecient. WebJun 15, 2016 · My problem is with DMA, I'm trying to make a burst from a source array variable to 4 MATCHREL registers (SCT Peripheral). The idea is simple, read the source array and do a burst of 4 words for the 4 MATHCREL, doing this continuasly, until the source ends. Very similar, with read the ADC fifo, for example, but is the inverse.

What Is Direct Memory Access (DMA) and How Does It Work?

WebMar 22, 2024 · DMA has three modes of operation: burst mode, cycle stealing mode, and transparent mode. Burst mode. In burst mode, the DMA controller takes control of the bus for a short time to perform a data transfer. The CPU can still access memory, but there may be a brief delay while the DMA controller finishes its task. Cycle stealing mode.
