1Use of energy by moving object
If conventional digital processing methods are used for AI operations, then processing speed can be maintained, but power consumption increases and circuit complexity increases
Solution Approach 1:
The patent replaces conventional digital electronic processing with a pulse-based oscillation system. Digital input signals control oscillators to generate pulse trains, where the number of pulses represents computational results. This substitution of digital logic with physical oscillation phenomena reduces power consumption while maintaining processing capability for AI operations.
Solution Approach 2:
The system changes the parameter representation from digital voltage levels to pulse count and oscillation frequency. By varying the number of oscillation cycles and pulse widths rather than using digital bit representations, the system achieves low-power operation while performing product-sum operations essential for AI processing.
2Productivity
If more digital input signals are processed simultaneously, then processing capability increases, but circuit complexity increases
Solution Approach 1:
The patent employs a universal oscillator circuit that can process multiple digital input signals through a single integrated structure. The oscillator receives digital control signals and generates corresponding pulse trains, allowing one circuit to perform multiple product-sum operations that would traditionally require separate processing units for each input signal combination.
Solution Approach 2:
Multiple processing functions are merged into a single oscillator-based system. Rather than having separate circuits for each computational task, the patent combines multiplication, accumulation, and signal processing functions into the oscillation control mechanism, where the oscillator's response to digital inputs inherently performs the required computations.

AI summary
An information processing device has a digital-to-pulse converter which outputs a pulse signal including a pulse having a pulse length in accordance with a digital input signal, and a selective oscillator which performs an oscillation operation while the pulse of the pulse signal is output and holds an oscillation operation state at a point of time where the output of the pulse is stopped.
