AN84810 - PSoC® 3 and PSoC 5LP Advanced DMA Topics
AN84810 discusses several advanced PSoC® 3 and PSoC 5LP direct memory access (DMA) topics and design challenges.This application note builds upon the fundamental concepts introduced in AN52705 – Getting Started with DMA. Topics covered include indexed transfers, timing and bandwidth considerations, data alignment, and DMA debugging tips.
Introduction
Direct memory access (DMA) controllers transfer data between peripherals and memory without CPU intervention. The DMA controller (DMAC) in PSoC® 3 and PSoC 5LP features 24 channels and 128 transaction descriptors (TDs), making it very versatile for a wide variety of applications. PSoC Creator™, the development environment for PSoC, has tools including a DMA wizard and component APIs that make it easy to design complex DMA functions.
