	AdV* is the project to upgrade the VIRGO* interferometric detector of gravitational waves. We present a major upgrade consisting of the design of new control electronics of the seismic isolation systems called Super-Attenuators (SAs). SAs are mechanical structures used to insulate optical elements from seismic noise. The control electronics are used to manage sensors, actuators, and stepping motors placed in the SAs. The design effort resulted in a high-performance signal conditioning and processing platform (UDSPT) that enables users to implement hard real-time control systems. The form factor is a variation of a double compact Module PICMG AMC.0 R2.0 Advanced MC. The key features are a TI DSP embedded, two GE ports, an AMC Interface containing SRIO, and GE, an FPGA interfacing data converters through PCIe. Additionally, it includes six 24-bit 3.83 MHz ADC and six 24-bit 320 kHz DAC converters, with fully differential inputs and outputs. In a single local control unit - a single 6U x 19 crate - up to 72 ADC + 72 DAC channels supported by 720 GFLOPs are allocated.

AdV* is the project to upgrade** the VIRGO*** interferometric detector of gravitational waves. We present a major upgrade consisting of the design of new control electronics of the seismic isolation systems called Super-Attenuators (SAs)*. SAs are mechanical structures used to insulate optical elements from seismic noise. The control electronics are used to manage sensors, actuators, and stepping motors placed in the SAs. The design effort resulted in a high-performance signal conditioning and processing platform (UDSPT) that enables users to implement hard real-time control systems. The form factor is a variation of a double compact Module PICMG AMC.0 R2.0 Advanced MC. The key features are a TI DSP embedded, two GE ports, an AMC Interface containing SRIO, and GE, an FPGA interfacing data converters through PCIe. Additionally, it includes six 24-bit 3.83 MHz ADC and six 24-bit 320 kHz DAC converters, with fully differential inputs and outputs. In a single local control unit - a single 6U x 19 crate - up to 72 ADC + 72 DAC channels supported by 720 GFLOPs are allocated. A total of 20 local control units have been installed and currently are controlling ten SAs in the AdV detector.
