The best way to move multimedia data

Many embedded multimedia applications involve interaction between system control (typically a microcontroller's role) and signal processing?normally the role of a digital signal processor (DSP). A single embedded media processor can handle both types of tasks. Though it's tempting for programmers with only microcontroller experience to adopt a "hands-off" approach and simply use caches to manage the flow of code and data, it's best to carefully consider using the high-performance direct memory access (DMA) capabilities of a media processor instead.
