| The SPS (Smart Peripheral Switch) is a DMA engine. |
| It can move data in the following modes: |
| 1. Peripheral-to-Peripheral. |
| 2. Peripheral-to-Memory. |
| 3. Memory-to-Memory. |

| help |
| The BAM-DMA is used for Memory-to-Memory transfers. |
| The main use cases is RPC between processors. |
| The BAM-DMA hardware has 2 registers sets: |
| 1. A BAM HW like all the peripherals. |
| 2. A DMA channel configuration (i.e. channel priority). |

| No-Data-Path BAM is used to improve BAM performance. |
| NDP BAMs enables peripherals with fast fabric connectivity |
| to do the actual data transfer themselves, instead of the |
| BAM. |
