SB401-50

The SB401-50 bus interface module plays a crucial role in industrial control systems. It provides a data read and write interface between the AXI bus and the host controller, and has the data management mechanism of the DMA controller. This module is the interface for the processing system to access the host controller. The system accesses the eMMC chip by reading and writing the registers in the bus interface module. Specifically, the functions of the bus interface module include but are not limited to providing a host controller interface between the system host controller and the storage chip, enabling data transmission and control between the two. Implement DMA (Direct Memory Access) communication interface control to improve data transmission efficiency. Handle interrupt request signals to ensure timely response of the system to external events. Provide register units, and the system controls the storage chip by writing these registers. Provide FIFO (First In First Out) read and write channels with configurable FIFO depth ranging from 8 to 4069. Responsible for the detection and power control of storage chips to ensure their normal operation. The SB401-50 bus interface module is widely used in various industrial control systems and embedded systems, and is a key component for achieving efficient and stable communication between internal components of the system and between the system and external devices.
