Description
An FPGA- and software - based system has been developed for real-time data acquisition (DAQ) on numerous RF and other technical subsystems of the Advanced Photon Source (APS) accelerator. The software, called DAQ, is based upon the EPICS control system and is tightly integrated to FPGA hardware running on a Micro Telecommunications Architecture (TCA) platform. The FPGA hardware continuously streams data from RF systems over a Peripheral Component Interconnect Express (PCIe) bus as Direct Memory Access (DMA) transfers to a Micro-TCA- based Linux blade. DMA data transfers trigger the EPICS DAQ software running on the Linux blade to continuously stream data to the APS network using the EPICS 7 PVAccess protocol. The RF DAQ software is integrated with many distributed software services on the APS network including data storage, data visualization, and RF system monitor and control. Development of this system required the integration of FPGA firmware, electronics hardware, and software developed by multiple groups at multiple institutions.
