摘要： A non-transitory computer-readable recording medium recording an analysis program for causing a computer to execute a process includes: generating a program by embedding a command for storing a process log in a storage into a compiled program generated by compiling a source program including a display command instructing to display a object; specifying an operation command related to a database in association with identification information of the object based on the process log stored in the storage by the display command in execution of the program; analyzing the operation command to specify an access destination; and outputting, for every access destination, a correspondence including information indicating a type of the operation command in association with the identification information of the predetermined object.

摘要： A delay measuring instrument includes a generating unit and a calculating unit. The generating unit is, for example, a multiplier. The calculating unit is, for example, a maximum value detecting unit. The generating unit generates an intermediate signal by multiplying one of transmission signals or the complex conjugate of the one of the transmission signals included in the plurality of transmission signals that are transmitted at different frequencies by a reception signal that includes therein an intermodulation signal generated by the plurality of the transmission signals. The calculating unit calculates, based on a correlation value between the intermediate signal and the other one of the transmission signals included in the plurality of the transmission signals, an amount of delay of the other one of the transmission signals with respect to the intermodulation signal.

摘要： A plurality of floating-point registers store data therein. A processing execution unit executes arithmetic processing by using data stored in the floating-point registers. A first switch and a second switch select a route connecting the processing execution unit and the floating-point registers. A switch control unit controls the first switch and the second switch so as to switch a route to be selected, based on a switching instruction from the processing execution unit.
