The Data Acquisition Backbone Core (DABC) is a new GSI software framework to run data acquisition with distributed event building on high performance Linux clusters. Experimental data input is provided by means of generic Device and Transport interfaces. DABC offers elaborate mechanisms for multiprocessing, buffer management, and dataflow throttling. These are transparently available for all implemented...
Along with the rapid development of electronic technology and the constant improvement of user needs, the design of embedded system also faces more challenges. This paper mainly designs an embedded data acquisition system based on FPGA and its structure is as follows. It mainly includes three parts, namely AD, FGPA and embedded platform, FPGA is responsible for collecting, de-noising, accumulating,...
An ATCA-based computation platform for data acquisition and trigger (TDAQ) applications has been developed for multiple future projects such as PANDA, HADES, and BESIII. Each Compute Node (CN) appears as one of the fourteen Field Replaceable Units (FRU) in an ATCA shelf, which in total features a high performance of 1890 Gbps inter-FPGA onboard channels, 1456 Gbps inter-board backplane connections,...
