中文摘要：

面对不同应用场景,原始采样数据可能包含不同类型信号,而各种类型信号的处理也往往需要不同的数据帧结构。因此,需要对原始采样数据进行快速缓存,并根据数据处理的要求进行重组帧。在此使用可编程器件设计了结构化状态机对SDRAM进行读写控制,给出了一种便于FPGA实现的基于文件结构的数据缓存与重组帧方案。该方案已应用于某实际系统中,具有速度快、可靠性高的特点,并能灵活应用于其他存储系统中。

英文摘要：

For different applications, sampled data may contain different type signals, which need varied data frame structure to be processed. Therefore, flexible storage and reconstruction of the sampled data for dada processing are needed. A structural state machine was designed for storage control of SDRAM, which is based on a file structure data cache storage pro- gram with FPGA. Likewise, a reconstruction module of data frame structure is also realized. This new design is applied in a practical system with good performance in speed and reliability, and it also can be easily used in other storage systems with its flexibility.
