摘要
针对战斗部舱内相关参数的高速存储任务,设计了一种基于eMMC的高速固态存储系统。该系统以FPGA为控制芯片,实现接收和存储一体化数据综合器输出的PCM数据和图像数据的功能,提高系统的兼容性。与传统的存储系统相比,该系统的存储单元使用了eMMC器件,此器件集中了单块芯片上坏块检测和复杂的系统管理问题,与传统的Flash相比,使用更加方便。实验证明,基于eMMC的高速固态存储系统能够确保数据无误码可靠接收和存储,同时自身具备防护能力,能够适应落地冲击等恶劣环境。
A high-speed solid-state storage system based on eMMC is designed for high-speed storage tasks of relevant parameters in the warhead cabin.The system adopts FPGA as the control chip to realize the function of receiving and storing the PCM data and image data output by the integrated data synthesizer,thereby improving the compatibility of the system.Compared with the traditional storage system,the storage unit of the system utilizes the eMMC device,which concentrates on bad block detection and complex system management problems on a single chip,and it is more convenient to use than the conventional Flash.The experiment proves that the high-speed solid-state storage system based on eMMC can ensure reliable reception and storage of data without error,meanwhile,it has its own protection ability,which can adapt to harsh environments such as landing impact.
