Last time, in Part 1, we introduced somebasics behind Direct Memory Access (DMA) -why it's needed, and how it's structured and controlled. This time,we'll focus on the classifications of DMA transfers ...

In the world of computers, the central processing unit (CPU) is–well–central. Your first computer course probably explained it like the brain of the computer. However, sometimes you can overload that ...

This application note presents the Direct Memory Access (DMA) control, its basic set-up and operations. The document includes the usage examples of the DMA controller and the DMA Trigger Factor ...

Direct memory access (DMA) systems in computers are more powerful than you might think, and [Bruce Land] and [Joseph Primmer] have done some clever hacking to take full advantage of this on the PIC32 ...

Part 1 shows how to build a software framework, choose between cache and DMA, and partition instructions and data for optimal performance. Part 3 explains how to optimize code placement and data ...
