Synchronization Controller Design of HIRFL-CSR Based on ACEX1K50

The synchronization controller is the core component of Lanzhou HIRFL-CSR synchronous system. As the highest instruction unit and timing unit of HIRFL-CSR control system, it directs the entire system to do the proper thing at the proper time and requires the timing accuracy of nanosecond and very high stability of running. The methods of realizing the main function modules of synchronization processor and the key technologies by using hardware description language (VHDL) on ACEX1K50 chip were introduced. The test results and the actual applications were given.
