Abstract
The CDF Run II level-2 calorimeter trigger is implemented in hardware and is based on a simple algorithm used in Run I. This system has worked well for Run II at low luminosity. However, as the Tevatron instantaneous luminosity increases, the limitation due to the simple algorithm starts to become clear. In this paper, we will present an upgrade path to the level-2 calorimeter trigger system at CDF. This upgrade approach is based on the Pulsar board, a general purpose VME board developed at CDF and used for upgrading both the level-2 tracking and the Level-2 global decision crate. This paper will describe the design, hardware and software implementation, as well as the advantages of this approach over the existing system.
CDF Run II 2级量热计触发器在硬件上实现，并基于Run i中使用的简单算法，该系统在低亮度下运行良好。然而，随着Tevatron瞬时光度的增加，由于简单算法的限制开始变得清晰。在本文中，我们将介绍CDF的二级热量计触发系统的升级路径。这种升级方法基于脉冲星板，脉冲星板是CDF开发的通用VME板，用于升级2级跟踪和2级全局决策箱。本文将介绍该系统的设计、硬件和软件实现，以及该方法相对于现有系统的优点。
