Temperature data acquisition system cPCI-ACC

voltagebuilt-indigital I/O

CPCI-ACC is high performance real time processing card on cPCI standard. On the board there are 4 DSPs working in a systolic cluster and a FPGA for hardwired processing and microprocessor activity. Conversion is made through IF Analog to Digital path, where analog signal is sampled from AD at 150MPs/s. BF Analog signal is sampled too, using a 2.5MPs/s converter at 16 bits. RF signal is generated from DDS where inside there is a 1GHz NCO allowing the users to generate a wide spectrum of modulations, using I/Q datapath coming from FPGA/DSPs. A wide range of applications are permitted. A FPGA based microprocessor is developed using Microblaze ™ XILINX core, able to manage all the parts on the board. A full compliant cPCI bus standard allow the users to dialogue with more than one board over a cPCI backplane. (Microprocessor unit is needed). GPS receiver and a high stability OCXO guarantee that all the processing write inside FPGS/DSPs are synchronous or time referenced via a built-in NTP server. In the next hardware release the physical interface will be able to comply with the PTP protocol and enable the timestamping of real time events occurring in the host O.S. or triggered on the external SMB connectors.
