一种基于高速串行总线的大容量数据实时存储系统
摘要：
一种基于高速串行总线的大容量数据实时存储系统，包括接收控制模块、数据存储装置、高速串行总线及RS422总线，接收控制模块首先接收飞行器产生的指令，将其转译为指令帧后通过RS422总线转发给数据存储装置；然后接收飞行器产生的数据进行编帧后得到编帧数据，通过高速串行总线输出给数据存储装置。数据存储装置包括存储控制FPGA和FLASH阵列，存储控制FPGA根据接收的指令将编帧数据以多路并行的方式实时写入FLASH阵列中或对FLASH阵列中的数据进行读取，并通过总线下传。本发明提高了存储系统的数据带宽，满足飞行器遥测系统高速率数据传输的需求，同时采用FLASH阵列及FLASH读写流水线技术，保证了存储系统的大容量、高速率数据存储以及数据的可靠回收。
摘要（英）：

The invention provides a high-speed serial bus-based high-capacity data real-time storage system, which comprises a receiving control module, a data storage device, a high-speed serial bus and an RS422 bus, wherein the receiving control module firstly receives an instruction generated by a flight vehicle, translates the instruction into an instruction frame, forwards the instruction frame to the data storage device through the RS422 bus, receives data generated by the flight vehicle for frame editing to obtain frame-editing data, and outputs the data to the data storage device through the high-speed serial bus; the data storage device comprises a storage control FPGA and an FLASH array; and the storage control FPGA writes the frame-editing data into the FLASH array in a multi-channel parallel manner in real time according to the received instruction or reads the data in the FLASH array and downloads the data through the bus. According to the high-speed serial bus-based high-capacity data real-time storage system, the data bandwidth of the storage system is improved; the requirements of high-speed data transmission of an aircraft telemetering system are met; and meanwhile, high-capacity and high-speed data storage and reliable data recovery of the storage system are ensured by adopting the FLASH array and an FLASH reading and writing assembly line technology.
