Enhanced Direct Memory Access (eDMA)
20.1 Introduction
NOTE
For the chip-specific implementation details of this module's
instances, see the chip configuration information.
The enhanced direct memory access (eDMA) controller is a second-generation module
capable of performing complex data transfers with minimal intervention from a host
processor. The hardware microarchitecture includes:
• A DMA engine that performs:
• Source address and destination address calculations
• Data-movement operations
• Local memory containing transfer control descriptors for each of the 8 channels
