Engineering Contradiction Analysis
1Use of energy by moving object
If a single processing unit performs sequential sample synthesis operations, then device complexity is reduced, but power consumption per sample increases and processing speed decreases
Solution Approach 1:
The sample synthesis operation is divided into multiple stages (first stage, second stage, etc.), with each stage performed by a dedicated processing unit. This segmentation allows parallel execution of different stages, reducing the total time and energy required to generate each audio sample while distributing computational load across multiple units.
Solution Approach 2:
The patent transitions from sequential single-unit processing to parallel multi-unit processing by adding a temporal dimension to the computation pipeline. Multiple processing units operate simultaneously on different stages of sample synthesis, effectively converting a one-dimensional sequential process into a multi-dimensional parallel architecture.
2Productivity
If computational tasks are distributed across multiple processing units in parallel, then processing speed and efficiency improve, but device complexity and cost increase
Solution Approach 1:
The audio sample synthesis process is segmented into distinct computational stages, each handled by a specialized processing unit. This enables simultaneous execution of multiple stages, increasing the overall sample generation rate while keeping each individual processing unit relatively simple and manageable.
Solution Approach 2:
The first processing unit performs preliminary computational stages before passing intermediate results to subsequent processing units. This preliminary action allows later stages to begin processing earlier, overlapping computations in a pipeline fashion that accelerates overall sample generation without requiring all units to be fully complex.
3Duration of action of moving object
If sequential processing is used to simplify device architecture, then manufacturing cost is reduced, but battery life decreases due to higher per-sample power consumption
Solution Approach 1:
By segmenting the sample synthesis workflow into multiple stages executed by separate processing units, the system reduces the computational burden and power consumption associated with each individual sample generation event. This segmentation enables more efficient resource utilization and lower overall power consumption, extending battery life despite increased architectural complexity.
