The J-PARC LINAC introduced ACS (Annular-ring Coupled Structure) cavity and now available the 400 MeV beam extraction. As for the RCS (Rapid Cycling Synchrotron) the power supply of the injection magnets were replaced those can acceptable the 400 MeV beam injection. Because there occured many troubles of equipments in the early phase of the beam study, we desired to shorten the measurement time of the beam monitor to determine the parameters. In this report it is described the signal processing system of MWPM (Multi-wire profile monitor) which is used to measure the injection beam profile for better accuracy and shorter measurement time.
