Design on High Speed Data Acqucisition Storage Board

The mechanism and scheme of system in the designed storage board for high speed and large capacity are introduced.It uses a dual 8-bit analog-to-digital converter with a sample rate up to 1 GS/s,uses FLASH as storage medium and FPGA as the processor of the storage array.For high speed data input from A/D,the pipeline technique and the redundancy check method are used.Moreover,the invalid blocks of FLASH chips have been masked out too.It successfully accomplish the high speed data storage with the high density and relatively low speed FLASH chips.Besides,it can also communicate data with the computer host through the bridge chip PCI9656.
