Signal Processor Dynamic Channel Rerouting for Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In audio signal processing systems, resources for unused channels are often wasted due to underutilization, as they do not receive input audio signals, leading to inefficiencies in signal processing and potential delays when trying to increase processing effects.
Innovation Solution
A signal processor that includes a processor and memory to perform multiple tasks, such as input and signal processing tasks, which allows for automatic rerouting of processed audio signals from used channels to unused channels, enabling effective use of resources by performing signal processing on unused channels with processed audio signals from other channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If signal processing is performed for each channel with dedicated processing portions and memory, then signal processing quality is improved, but resource waste occurs when the number of input audio signals is smaller than the number of channels
Solution Approach 1:
The signal processing portion is designed to perform multiple functions by dynamically assigning processing tasks across different channels. When fewer audio signals are input than the number of channels, the control portion redirects processed signals from active channels to inactive channels, enabling the signal processing portion to serve both active and inactive channels effectively, thus eliminating resource waste while maintaining processing quality.
Solution Approach 2:
The system implements dynamic channel assignment where the control portion monitors the number of input audio signals and adjusts the allocation of signal processing tasks in real-time. The processed audio signal from an active channel can be dynamically output to an inactive channel's signal processing portion, creating a flexible resource allocation system that adapts to varying input conditions.
2Productivity
If additional signal processing effects are added to increase processing capability, then signal processing effectiveness is improved, but processing delays increase
Solution Approach 1:
The system merges the processing capabilities of multiple channels by outputting processed audio signals from active channels to inactive channels. This allows the accumulated processing effects from multiple signal processing portions to be combined and applied to the same audio signal, increasing processing effectiveness without adding sequential processing steps that would cause delays.
Solution Approach 2:
By continuously utilizing inactive channels to process and output processed signals from active channels, the system maintains continuous useful action throughout all channels. This parallel processing approach ensures that processing effects are accumulated without introducing additional processing time, as the inactive channels are already operating continuously and can immediately contribute their processing capabilities.

AI summary
A signal processor and a signal processing method thereof. The signal processor obtain a first audio signal of a first channel, obtains a second audio signal of a second channel. The signal processor performs a first signal processing on the input first audio signal. The signal processor, when it does not obtain the second audio signal, performs a second signal processing on the input first audio signal having undergone the first signal processing and output a further processed first audio signal.
