Abstract

We present the development of the global trigger emulator system (eGTP) of the CMS data acquisition system (DAQ). The eGTP generates level-1 triggers and exchanges information with other DAQ components. The eGTP is based on a multi-purpose PCI board (generic PCI platform III) built around an FPGA, hosted in a PC. The board is programmed to function as a trigger summary pseudo-data source with partitioning capabilities. Data transmission is achieved via the SLINK-64 protocol. The eGTP aims at decoupling the level-1 trigger system from the readout system, for testing, installation and maintenance purposes.
