摘　　要：为了弥补传统的NAND Flash芯片存储容量小、速度低以及体积大的不足,设计了高速大容量eMMC的数据读取与缓存系统。该系统中eMMC芯片具有体积小、性能稳定以及存储速度快等特点,可用于实时存储接收到的外界数据信息。经过测试,存储容量可以达到60 GB,读写速度可以达到80 MB/s,实现了小型化、大容量、高速多信号数据采编、高传输速度以及高过载性。目前已经在某项目中得到应用。To compensate for the shortcomings of traditional NAND Flash chips such as small storage capacity,low speed,and large volume,a high speed and large capacity eMMC data reading and caching system is designed.The eMMC chip in the system has the characteristics of small size,stable performance and fast storage speed.It can be used to store the received external data information in real time.After testing,the storage capacity can reach 60 GB and the read/write speed can reach 80 MB/s,realizing miniaturization,large capacity,high-speed multi-signal data collection and editing,high transmission speed and high overload.It has already been used in a project.
