Because the DMA controller operates on the bus matrix alongside the CPU, it ensures data moves at predictable speeds. The Arm Cortex-M DMA Architecture
The DMA controller functions as a "secondary master" on the microcontroller's bus matrix. It shares access to memory and peripherals with the CPU, using an arbiter to manage who gets control of the bus at any given millisecond. Key components include: Because the DMA controller operates on the bus

The CPU is free to perform complex calculations or enter low-power sleep modes while data moves in the background. Because the DMA controller operates on the bus
