摘　　要：在数据采集记录装置中, FPGA芯片具有强大的并行处理能力。因此在快速发展的今天,数据采集工作是针对多种类型的数据进行混合采集,已经不再是对单一类型数据的采集。通过设计数据混合编帧的方案,同时分析不同种数据缓存,最终结果确立了基于FIFO的缓存结构,将不同类型的数据汇合为一路进行高速可靠的传输。经过大量的不同类型的试验结果验证,以及对回读的数据分析,没有出现过任何数据丢失、丢包、误码等现象,符合所给任务要求。In data acquisition and recording devices, FPGA chips have powerful parallel processing capabilities. Therefore, in the rapid development of today, data collection work is no longer a single type of data collection, but a variety of types of data for mixed collection. By adopting the scheme of mixed frame-making and analyzing different data caches, finally establishes the cache structure based on FIFO, and converges different types of data into one way for high speed and reliable transmission. After a large number of different types of experiments, as well as back-reading data analysis, there has been no data loss, packet loss, error code and other phenomena, in line with the task requirements.
