Nowadays gigabit Ethernet is widely used in the area of computer and industry communication. In order to resolve the bandwidth of data transfer in high-speed data acquisition system, this paper introduces design principles and implementation methods of gigabit Ethernet interface based on FPGA. The physical layer hardware realization and the MAC layer realiz ation are described in detail. At last,...
To satisfy the need of on-board accumulation in time-of-fLight mass spectrometer (TOF-MS) appLications, the paper presents an accumulation algorithm in FPGA based on PipeLine and ping-pong operation. The accumulation algorithm is verified on a signal averager hardware platform which takes XILiNX VIRTEX-5 FPGA as the processing core. The caChe module, on-chip accumulation, and USB transmission module...
This paper presented a high speed data acquisition system for real-time appLication. The hardware of system mainly consists of data acquisition, distribution and storage section. A 3Gsps ultra high-speed ADC is appLied in acquisition section. In distribution section, the original data stream will be distributed into four streams. Each data stream will be stored into one soLid-state storage card which...
