摘要:

我们研制了一种基于现场可编程门阵列和复杂可编程逻辑器件的快速可编程触发处理器板,用于BELLE实验。触发板可容纳144个ECL输入信号、2个NIM输入信号、24个ECL输出信号和VME总线规格。使用异步触发逻辑来对孤立的簇进行计数。我们已经获得了50 ns的触发延迟与通过VME接口的输入和输出信号的完全访问。触发逻辑可以根据实验条件随时修改。

英文摘要:

We have developed a fast programmable trigger processor board based on a field programmable gate array and a complex programmable logic device for use in the BELLE experiment. The trigger board accommodates 144 ECL input signals, 2 NIM input signals, 24 ECL output signals, and the VME bus specification. An asynchronous trigger logic for counting isolated clusters is used. We have obtained trigger latency of 50 ns with a full access to input and output signals via a VME interface. The trigger logic can be modified at any time depending on the experimental conditions.
