USB bus has been widely used for such features as plug-in and play, easy extensions and high transmission rate (480Mbps in the protocol of USB2.0). The USB controller CY7C68013 is used widely because it has high speed and various interfaces: FPGA, ATA and DSP and so on. The paper introduces how to implement the interface of CY7C68013 and FPGA by hardware description language (HDL). By means of CY7C68013's...
The Global Tracking Unit of the ALICE Transition Radiation Detector is a high-speed, low-latency trigger processor installed at the ALICE experiment at the Large Hadron Collider. Based on the analysis of up to 20,000 parametrized particle track segments per event, a trigger decision is formed within approx. 2 μs. Furthermore, the system is designed to significantly improve the overall detector performance...
The EnDat2.2 interface protocol developed by HEIDENHAIN company lately with its high-speed, bi-directional and pure digital features can meet the requirement of rapid responses, dramatically cut down the overall system's cost and greatly reduce the space requirements of the system's installation. Therefore, it is widely used in Numerical control system like CNC system and photoelectric encoder. China's...
This paper describes a high-speed data acquisition and processing system which has been successfully operated on the multi-spectral imagery system. The system, which is based on PCI-E interface, can collect data as 280 MBps and store over 60 minutes per times without losing frames. This study discusses several main problems during hardware design and software design.
Recently, in the field of geological exploration, electromagnetic instruments have been tremendous growth, but they also have some typical shortcomings, such as big size, large power consumption, complex operation and so on. Therefore, base on the current development of electronic technology, this paper has discussed hardware and software design of the electromagnetic data acquisition system, which...
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,...
