  ZYNQ is the new architecture of FPGA with dual high performance ARM Cortex-A9 processors from Xilinx. A new module with Giga Bit Ethernet interface based on the ZYNQ XC7Z010 is development for the High Purity Germanium Detectors' data acquisition in the CJPL (China JingPing under-ground Lab) experiment, which is named as RAIN1000Z1. Base on the nice RAIN1000Z1 hardware platform, EPICS is porting on the ARM Cortex-A9 processor with embedded Linux and an Input Output Controller is implemented on the RAIN1000Z1 module. Due to the combination of processor and logic and new silicon technology of ZYNQ, embedded Linux with TCP/IP sockets and real time high throughput logic based on VHDL are running in a single chip with small module hardware size, lower power and higher performance. This paper will introduce how to porting the EPICS IOC application on the ZYNQ based on embedded Linux and give a demo of IO control and RS232 communication.

  Neutrino research is of great importance for particle physics, astrophysics and cosmology, the JUNO (Jiangmen Underground Neutrino Observatory) is a multi-purpose neutrino experiment for neutrino mass ordering determination and precision measurement of neutrino mixing parameters. A brand new global trigger scheme with online vertex fitting has been proposed, aiming at the ultra-low anti-neutrino energy threshold as down to 0.1MeV which is essential for the study of solar neutrino and elastic scattering of neutrinos on supernova burst. With this scheme, the TOF (time of flight) difference of photons fly through the liquid media from the interaction point to the surface of central detector can be corrected online with real time, the width of trigger window to cover the whole period of a specific neutrino generated photons can be significantly reduced which lessen the integrated dark noise introduced from the large amount of PMT devices hence a lower energy threshold can be achieved. The scheme is compatible, flexible and easy to implement, it can effectively extend the physics potential of the JUNO for low energy neutrino research topics.
