为CDF升级设计了一个名为极快跟踪器(XFT)的触发跟踪处理器。该处理器在CDF II新的中央外部跟踪室中识别高横向动量(&gt；1.5GeV/c)带电粒子。XFT设计高度并行，可以处理183Gbit/S的输入速率和44Gbit/S的输出速率。处理器是流水线结构，每132 ns报告一次新事件的结果。处理器使用三个阶段：命中分类、片段查找和片段链接。这三个阶段的模式识别算法在可编程逻辑器件(PLD)中实现，允许在任何时间对算法进行原位修改。PLD位于三种不同类型的模块上。整个系统已经在CDF II上安装和调试。CDF Run II中的航迹处理器和性能的概述。
A trigger track processor, called the eXtremely Fast Tracker (XFT), has been designed for the CDF upgrade. This processor identifies high transverse momentum (>1.5 GeV/c) charged particles in the new central outer tracking chamber for CDF II. The XFT design is highly parallel to handle the input rate of 183 Gbits/s and output rate of 44 Gbits/s. The processor is pipelined and reports the result for a new event every 132 ns. The processor uses three stages: hit classification, segment finding, and segment linking. The pattern recognition algorithms for the three stages are implemented in programmable logic devices (PLDs) which allow in-situ modification of the algorithm at any time. The PLDs reside on three different types of modules. The complete system has been installed and commissioned at CDF II. An overview of the track processor and performance in CDF Run II are presented.
