基于高速eMMC存储的弹载记录仪设计
Design of missile-borne recorder based on high-speed eMMC storage
摘要
Abstract
Missile-borne recorder is the key device of projectile. To rapidly and accurately record acceleration and angular velocity flight parameters on projectile opening,a design scheme of the missile-borne recorder based on high-speed eMMC storage is proposed in this paper. The overall hardware architecture and software workflow of the system are introduced. The de-sign of data read-write logic for single-block eMMC is emphatically studied. The serial mode is adopted for data transmission be-tween FPGA and eMMC storage. A six-channel acquisition system with high-speed read-write,low power consumption and high integration is achieved,whose write-in speed is 20 MB/s,read-out speed is 44 MB/s,and storage capacity is 32 GB. The experi-mental results demonstrate that this design can fully read the data with 30 000 g impact.关键词
