Description
A MWPC readout system is designed for a high trigger rate fixed target experiment E871 in Fermilib in US. The system is pipeline structured which includes signal latch, derandomize FIFO, encoder and buffers, and has the dead time less then 0.47 μs. The system is composed of two daisy-chained crates in which there are multiple FEM modules and their interface FEMI. 128 channels of the wire signals are received and processed by each FEM. Fore reducing the readout time, the daisy-chain circuit is used readout the relatively sparse data. The operations are accomplished by the hardware. A series of events are processed in different stages at the same time and is continuously passed through the MWPC readout system. The system has been fully tested. 109 fake events were received and processed without fault at 250 kHz trigger rate
