基于USB总线的超高速数据采集及实时处理系统采用双核结构在保证采样率不变的情况下,降低了系统数据传输速率,减轻了后续存储系统的压力。采用可编程逻辑器件作为系统的控制处理器,提高了系统的运行速率,简化了系统设计。并且提高了系统可靠性。作为工作频率为1GHz的系统,必须考虑其电磁兼容性及信号完整性问题,通过对反射,延迟以及串扰的控制使系统达到了设计要求。
Ultra-high-speed USB-based data acquisition and real-time processing system uses dual-core structure to ensure that the sampling rate unchanged, reducing the system data transfer rate and reduce the pressure on the subsequent storage system. The use of programmable logic devices as the system’s control processor to improve the system’s operating speed and simplify the system design. And improve system reliability. As a system operating at 1 GHz, the issue of electromagnetic compatibility and signal integrity must be considered, and the system meets the design requirements by controlling reflection, delay, and crosstalk.
