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.
