Abstract(in English) | As the amount of data traffic through the communication infrastructure is increasing, a development of high-speed information and communication apparatus enabling to handle large volumes of data is required. An information and communication apparatus has a lot of programmable devices such as FPGAs because of their design flexibility. On the other hand, use of high-speed and well-integrated FPGA faces a growing risk of malfunction caused by terrestrial-neutron induced soft errors. In a conventional method for mitigating soft errors, configuration memories (CRAM) which is the weakest circuit in FPGAs is scanned and corrected by circuit IP provided by FPGA vendors. However, multi-die FPGAs have large volume of CRAMs resulting long time to recover soft errors. In fact, it is difficult to guarantee a continuity of services while recovering system operation. This time, we developed a novel circuit IP, called CRAM-control engine, which recovers soft errors in short time by controlling CRAM areas to be scanned and scan-sequence. In this report, we introduce an overview of our developed IP and its features, and report confirmation results of the efficiency of our IP by neutron-irradiation tests. |
