Abstract


Information storage technology which has high capacity, low power consumption, high speed, high density, and low cost attributes is one of the most significant components in information acquisition, fusion, transmission, and processing of satellite and other aerospace equipment. In addition, this technology also can be used in variety of research areas. Magnetic tape was used in massive data recording in early stage. Furthermore, space powers began to research and use magnetic disk, magneto optical disk, and solid state disk until late 1980s to early 1990s. Otherwise, with the development of micro-electronic technology and increasing storage density of semiconductor memory. FLASH and DRAM based mass solid state storage is considered as an major solution in data recording and storage. However, there are five major technical issues should be resolved to meet the demand of massive data storage viz. how to build and manage mass storage device effectively; how to increase transmission rate in both input and output process; how to reduce volume and weight by increasing mounting density of storage device; how to decrease power consumption; and how-to enhance the efficiency of error correction encoding technique.This article studied and proposed a high speed and large capacity data storage system based on macroscopic design principle of mass memory measurement system as well as system state design theory. The major concerns of proposed system are signal measurement and data storage during On-board diagnostic process. These signals include 12 circuit vibration,4 circuit shock response signal, and 4 circuit noise signal. Moreover, the collected data could be stored in long time period for further retrieve and read. After a competitive analysis of latest related domestic and external reference as well as application requirements, this article proposed a FLASH based, high speed high capacity data storage design and implementation scheme. The proposed design and scheme have been given adequate consideration in integration of domestic actual situation and FLASH’s technical characteristics. Particularly, the pipeline operation and bus-width expansion technique are used in the proposed design. In addition, high performance FIFO is used to buffer high-speed data flow fluctuation and monolithic FPGA is used to realize system logic control. Finally, since the modular design method is used, the proposed design and scheme with the characteristic of portable and flexibility.
