A general xTCA compliant and FPGA based data processing building blocks for trigger and data acquisition system

This paper describes a general purpose xTCA compliant and FPGA based Data Processing building blocks to be used for trigger and data acquisition system in a big physics experiment with characteristic of high speed data transmission and processing. It features large Field of Programmable Gate Array (FPGA) for data processing, DDR2 memory for data buffering, RocketIO and Gbit Ethernet for data transmission and Intelligent Platform Management Controllers (IPMC)/Module Management Controllers (MMC) for managing the hardware and power. IPMC/MMC are designed on an add-on card with the function of power management, temperature sensing and some other module monitor function. A single ATCA shelf can host up to 14 units interconnected via a full mesh backplane.
