Abstract :
A readout system suitable for a large number of synchronized photo-detection units has been designed. Each unit embeds a specifically designed fully integrated communicating system based on Xilinx FPGA SoC technology. It runs the VxWorks real-time OS and a custom data acquisition software designed within the Ice middleware framework, resulting in a highly flexible, controllable and scalable distributed application. Clock distribution and delay calibration over customized fixed latency gigabit Ethernet links enable synchronous time-stamping of events with nanosecond precision. The implementation of this readout system on several data-collecting units as well as its performances are described.
