The Micro Direct Memory Access (μDMA) controller allows for data transfer tasks to be offloaded from the microcontroller core which results in more efficient use of the processor and memory bus. This enables programmers to minimize CPU cycles for certain tasks like peripheral-to-memory and memory-to-memory transfers. These benefits can greatly help to optimize a system using an RTOS. Three examples are provided to show how to use the μDMA in various modes as well as demonstrate both types of memory transfers.
