| Abstract: | In this thesis, a PCI based high speed data acquisition system is introduced. The system use an AD90S4 chip with sampling rate of 100MHz and a FIFO chip with read/wite cycle of 10ns. High speed ispLSI PLD chip is utilized to realize the sampling window and other logic control circuit. Low Voltage Differential Singnaling technology conformed to TIA/EIA -644 standard is used to transform the data. The data is stored to computer disk via PCI interface, which is based on field programming gate array chip. |
