基于网络技术的数据采集系统已被开发用于实验，该实验使用来自SPring-8的激光与8 GeV电子之间的后向康普顿散射的高能光子。设计了一个通用I/O VME板（UIO），它是一个具有可重构逻辑电路和1 Mbyte存储器的缓冲-定序器模块。UIO作为高速模块用于灵活的数据读出和缓冲。来自各种探测器的数据以通用格式从UIO传输到VME CPU板。Altera硬件描述语言用于从TOF计数器和切伦科夫计数器的快速编码和读出ADC（FERA）系统读取数据。
A data acquisition system on the basis of network technologies has been developed for experiments using high-energy photons from backward-Compton scattering between laser lights and 8 GeV electrons at SPring-8. A universal I/O VME-board (UIO) is designed as a buffer-sequencer module with a reconfigurable logic circuit and a 1 Mbyte memory. The UIO is applied as a high-speed module for flexible data readout and buffering. Data from the various detectors are transferred from the UIO to a VME CPU-board in the common format. Altera Hardware Description Language is used to read data from a fast encoding and readout ADC (FERA) system for TOF counters and Cherenkov counters.
