The RFX-mod2 Nuclear Fusion experiment is an upgrade of RFX-mod, shutdown in\n2016. Among the other improvements in the machine structure and diagnostics, a\nlarger number of electromagnetic probes (EMs) is foreseen to provide more\ninformation about plasma instabilities and to allow an improved real-time\nplasma control. An Analog to Digital Converter (ADC) architecture able to\nprovide at the same time both transient recording and real-time streaming, as\nwell as FPGA-based time integration of the inputs is foreseen in RFX-mod2.\nTransient recording provides full speed data acquisition (up to 1 MSample/s) by\nrecording data in local memory and reading memory content after the plasma\ndischarge. Real-time streaming of sub-sampled data is required for active\ncontrol. The chosen technology is based on the XILINX Zynq architecture that\nprovides in the same chip a multi-core ARM processor tightly coupled to a FPGA.\n Time critical functions are carried out by the FPGA, such as the management\nof the circular data buffer, low pass filtering for subsampling of the samples\nto be streamed and digital integration. Other functions are carried out by the\nprocessor, such as the management of the configuration setting, received via\nTCP/IP or HTTP, the data readout of acquired samples in transient recording\nbuffers and network data streaming of data collected for active real-time\nplasma control.\n
