Mountable controller with parallelized VERSA Module Eurocard (VME) (MPV) is a VME-compatible system having a parallel readout architecture. This article presents the system architecture and its data acquisition performance. In this system, the readout sequence is implemented in a field-programmable gate array (FPGA) to achieve the ideal VME bus speed. Data from multiple VME slave modules are read out in parallel, merged, and sent to a server. Maximum data throughput of 400 Mbps was achieved. Thus, the MPV system can dramatically improve the performance of VME data acquisition systems.
