A high performance FPGA based platform has been developed for the RHIC Low Level RF system upgrade, and is now replacing our aging VME based systems. This new platform employs a sophisticated embedded architecture to implement its core functionality. This architecture provides a control system interface, manages remote access to all configuration parameters and diagnostic data, supports communication between all system components, enables real time application specific processing, monitors system health, etc. This paper will describe the embedded architecture and its capabilities, with emphasis on its application at RHIC.

Due to the humid environment, condensation frequently occurs and ice was quickly formed during operation, especially during an extensive storage period. This condition generated warnings and alarms that personal had to respond to, in order to provide temporary solutions, to keep the machine operational.
