Abstract
A signal processing device includes a first memory storing waveform data; a second memory to which the waveform data is being transferred; and a processor configured to execute a first program that imparts a sound effect to samples of the waveform data that have been transferred to the second memory, and a second program that performs burst access to a plurality of samples of the waveform data stored in the first memory so as to transfer the plurality of samples of the waveform data to the second memory, wherein the processor determines an execution schedule of the second program such that a process execution of the first program and a process execution of the second program are respectively completed once in every sampling period of the waveform data.
Claims13
A signal processing device, comprising:
- a first memory storing waveform data;
- a second memory to which the waveform data is being transferred;
- and
- a processor configured to execute a first program that imparts a sound effect to samples of the waveform data that have been transferred to the second memory, and a second program that performs burst access to a plurality of samples of the waveform data stored in the first memory so as to transfer the plurality of samples of the waveform data to the second memory,
- wherein the processor determines an execution schedule of the second program such that a process execution of the first program and a process execution of the second program are respectively completed once in every sampling period of the waveform data.
A method of signal processing executed by a processor in a signal processing device that includes, in addition to the processor:
- a first memory storing waveform data;
- and a second memory to which the waveform data is being transferred, the method comprising, via the processor:
- executing a first program that imparts a sound effect to samples of the waveform data that have been transferred to the second memory, and a second program that performs burst access to a plurality of samples of the waveform data stored in the first memory so as to transfer the plurality of samples of the waveform data to the second memory;
- and
- determining an execution schedule of the second program such that a process execution of the first program and a process execution of the second program are respectively completed once in every sampling period of the waveform data.
A non-transitory computer readable storage medium storing instructions to be executed by a processor in a signal processing device that includes, in addition to the processor:
- a first memory storing waveform data;
- and a second memory to which the waveform data is being transferred, the method comprising, via the processor, the instructions causing the professor to perform the following:
- executing a first program that imparts a sound effect to samples of the waveform data that have been transferred to the second memory, and a second program that performs burst access to a plurality of samples of the waveform data stored in the first memory so as to transfer the plurality of samples of the waveform data to the second memory;
- and
- determining an execution schedule of the second program such that a process execution of the first program and a process execution of the second program are respectively completed once in every sampling period of the waveform data.
