Abstract
his paper introduces some applications of imbedded technology, and massive data collection and storage system based on master and slave MCU hardware structure. When the system is not connected to the computer, then master MCU takes the responsibility for reading the dual-port RAM and writing the data to IDE-FLASH-DISK. Otherwise the master MCU communicate with the computer by USB. The slave MCU takes the responsibility for communicating with AD chip by SPI and writing the data to the dual-port RAM. Because the using of dual-port RAM, the system can collect and store the data at a high speed. The system has the characteristics of low power, small size and working at a high speed.
