Engineering Contradiction Analysis
1Productivity
If separate units for multiplication and summation operations are used, then the device structure is simple and clear, but the processing units are underutilized and overall performance is limited
Solution Approach 1:
The patent applies multi-functionality by designing processing units that can perform both multiplication and summation operations. Each processing unit includes a preprocessing part with a selection operator and a shift operator, allowing the same unit to dynamically switch between multiplication mode (using shift operator) and summation mode (using selection operator), thereby eliminating the need for separate dedicated units and improving utilization efficiency
Solution Approach 2:
The patent merges previously separate multiplication and summation units into a single integrated processing unit. By combining the preprocessing part with both selection and shift operators, the patent consolidates multiple functions into one unit, reducing hardware redundancy while maintaining the capability to perform both operation types efficiently
2Productivity
If data exchange between processing units is restricted, then the hardware complexity is reduced, but the overall performance of the parallel processing device is limited
Solution Approach 1:
The patent segments data exchange functionality into standardized input and output interfaces for each processing unit. Each unit has defined data input terminals and output terminals with standardized connection protocols, allowing modular data exchange that simplifies the overall system architecture while enabling flexible inter-unit communication for improved performance
