摘要
探讨了高速数据采集系统中高速采样缓存的重要性和实现途径 ,阐述了基于ADSP -21065L的并行多通道数据采集板上高速采样缓存的设计与电路结构 ,给出了采用FPGA实现通道复用和采样数据预处理 ,从而构造16MB的SDRAM海量缓存以将高速缓存中的多批次采样数据经AD SP
The importance and implmentation of A/D cache and bulk memoryin high speed data acqucisition sysˉtemis discussed,and the design and circuit structure of high speed sample cache based on parallel multi-chanˉnel data acquisition of ADSP-21065L is given in this paper.Reusing channel and sample data pre-process to construct16MB SDRAMbulk cache is also introduced,and they can make high-speed sample data cache into SDRAMmemory through ADSP-21065L.
