Abstract
An arithmetic processing apparatus according to the present disclosure includes a digital filter. The arithmetic processing apparatus further includes a dummy data input unit configured to input dummy data to the digital filter when there is no input data input to the digital filter. The arithmetic processing apparatus further includes a cancellation processing unit configured to perform, on output data output from the digital filter, arithmetic processing for canceling an output component caused by the dummy data.
Claims7
An arithmetic processing apparatus comprising:
- a digital filter;
- at least one memory storing instructions;
- and
- at least one processor configured to execute the instructions to:
- in a first case where there is no input data that is input to the digital filter,
- input dummy data to the digital filter, and
- perform, on output data that is output from the digital filter, arithmetic processing for canceling an output component caused by the dummy data;
- and
- in a second case where the at least one processor is not able to determine whether or not there is no input data that is input to the digital filter,
- calculate a signal power of an input signal that is input to a buffer configured to transmit the input data, and
- in a case where the calculated signal power of the input signal is equal to or less than a threshold, input the dummy data to the digital filter.
An arithmetic processing method comprising:
- in a first case where there is no input data that is input to the digital filter,
- inputting dummy data to a digital filter, and
- performing, on output data that is output from the digital filter, arithmetic processing for canceling an output component caused by the dummy data;
- and
- in a second case where the at least one processor is not able to determine whether or not there is no input data that is input to the digital filter,
- calculating a signal power of an input signal that is input to a buffer configured to transmit the input data, and
- in a case where the calculated signal power of the input signal is equal to or less than a threshold, inputting the dummy data to the digital filter.
A non-transitory computer readable medium storing a program for causing an arithmetic processing apparatus to:
- in a first case where there is no input data that is input to the digital filter,
- input dummy data to the digital filter, and
- perform, on output data that is output from the digital filter, arithmetic processing for canceling an output component caused by the dummy data;
- and
- in a second case where the at least one processor is not able to determine whether or not there is no input data that is input to the digital filter,
- calculate a signal power of an input signal that is input to a buffer configured to transmit the input data, and
- in a case where the calculated signal power of the input signal is equal to or less than a threshold, input the dummy data to the digital filter.
