26 Operation Theory

4.1 Trigger Board Overview

The input and output relationships are shown as follows:

Inside the PCI-8124-C, all the position comparison and mapping

tasks will be executed within the FPGA. The functional block is as

follows:

The FIFO will automatically load the comparing points into 32-bit

comparator. The comparator will compare the data from counter
