【Abstract】 According to the requirements of a transient feeble optical signal detection system, a design approach is presents for control logic of the system. The approach taken FPGA technology as the core and programmed on the module means is used in order that the function of system control is implemented. As a result of the simulation and the test,the waves of them are furnished for some key signals such as ens,ad_ clk,oe and hbe. With the analysis and measurement of the guide line e. g. ,the switch of signal processing channels,the circuit delay,and the power dissipation,there is evidence that the design may be characterized by real-time,high-integration and -reliability,low-dissipation,flexibleness. The approach is applied in some transient feeble optical signal detection system successfully.更多还原
