摘要
文章介绍了一种实时持续数据记录系统的原理设计和基于FPGA的实现方法。在此类实时数据记录系统中,实时性和吞吐率是设计中的两个关键问题。为达到实时数据流记录的目的,在分析了传统系统设计的I/O瓶颈后,提出了一种新型存储系统结构以缩短数据存取路径,提高系统性能,并用FPGA予以实现。这种新的存储系统结构和基于FPGA的实现方法可以应用其它要求保证数据实时存储的领域以提高系统性能。
A new architectur e for high-speed sustained data recording system and its FPGA implementation ar e present in this article.As real-time and high throughput are required in such systems ,a new system framework based on FPGA is present to reduce the s ystem resource utilization and data transfer latency,contrarily resulting in th e improvement of the sustained data recording speed.All of the storage tasks a re completed by the high throughput data recording channel implemented on a sin gle FPGA chip without the intervention of the host-side software to satisfy th e real-time requirement.The proposed architecture and imple-mentation approa ches can be adopted in many applications where high-speed sustained acquisition data should be real-time recorded.
