FASTBUS是一个标准化的模块化数据总线系统，用于数据采集、数据处理和控制。FASTBUS系统由多个总线段组成，这些总线段可以独立运行，但连接在一起以传递数据和其他信息。FASTBUS可以使用握手协议异步运行，以可靠地适应不同速度的设备，而无需事先了解它们的速度。它还可以在不握手的情况下同步运行，以最大速度传输数据块。

FASTBUS is a standardized modular data-bus system for data acquisition, data processing, and control. A FASTBUS system consists of multiple bus segments that can operate independently, but link together for passing data and other information. FASTBUS can operate asynchronously using a handshake protocol to reliably accommodate different speed devices without prior knowledge of their speed. It can also operate synchronously without handshake for transfer of data blocks at maximum speed.
