SB401-50总线接口从模块是指只能被主设备访问的设备，只能响应主设备发来的总线命令。

SB401-50总线标准是为计算机系统的各个模块提供统一的接口标准，该接口对两端的模块都是透明的，即任何一方只需根据总线的标准，实现自身一方的接口功能，而不必考虑对方接口的功能实现。总线的主模块是获得总线控制权的设备；而总线的从模块是只能被主设备访问的设备，只能响应主设备发来的总线命令。

SB401-50总线接口部件的用途是什么

SB401-50总线接口部件的用途是负责与存储器和I/O端口传送数据。

SB401-50总线接口部件是从CPU送出的数据送到内存储器或I/O端口，或者将内存储器或I/O端口中的数据送到CPU，这些操作都由总线接口部件负责传送。SB401-50总线接口部件主要包括4个段地址寄存器、一个指令指针寄存器IP、一个20位地址加法器、6字节指令队列、内部通信寄存器和总线控制逻辑。

The SB401-50 bus interface slave module refers to the device that can only be accessed by the master device and can only respond to the bus commands sent by the master device.

SB401-50 bus standard is to provide a unified interface standard for each module of the computer system, the interface is transparent to both ends of the module, that is, any party only according to the bus standard, to achieve its own side of the interface function, without considering the other side of the interface function. The main module of the bus is the device that obtains the control of the bus. The slave module of the bus is a device that can only be accessed by the master device and can only respond to the bus command sent by the master device.

What is the SB401-50 bus interface component used for

The SB401-50 bus interface unit is used to transfer data to memory and I/O ports.

The SB401-50 bus interface unit is responsible for sending data from the CPU to internal memory or I/O ports, or sending data from internal memory or I/O ports to the CPU. The SB401-50 bus interface unit consists of four segment address registers, an instruction pointer register IP, a 20-bit address adder, a 6-byte instruction queue, an internal communication register, and bus control logic.
