The Global Trigger Processor Emulator System for the CMS Experiment.

We present the development of the global trigger processor emulator system (GTPe) for the CMS experiment data acquisition system (DAQ). The GTPe generates Level-1 triggers and exchanges information with other DAQ components. The GTPe is an FPGA-based PCI card operating in a host Linux PC. The board is programmed to function as a trigger data source, capable of generating multiple independent triggers and their associated data streams. Data are transmitted over the CMS-specific S-LINK64 protocol. The purpose of the GTPe is to decouple the Level-1 trigger system from the readout system. This is an important component of the installation, testing, and maintenance of the CMS DAQ. [ABSTRACT FROM AUTHOR]
