Processor Ones Detector Circuit Bypassing Multiplication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current processor architectures face inefficiencies in performing multiplication operations where one or both operands are 'one', leading to unnecessary power consumption and performance overhead due to the execution of these operations.
Innovation Solution
Incorporating a 'ones' detector circuit and 'ones' multiplier circuit within the processor architecture, which allows for the skipping of multiplication operations when both operands are 'one', thereby optimizing power usage and performance by turning off the multiplier circuit in such cases.

Engineering Contradiction Analysis
1Use of energy by moving object
If the processor executes multiplication operations for all input pairs, then the processing completeness is maintained, but the power consumption increases unnecessarily
Solution Approach 1:
The detector circuit performs a preliminary check before the multiplication operation to determine if either operand is one. This preliminary detection allows the system to skip the multiplication operation when both inputs are one, thereby avoiding unnecessary power consumption while maintaining processing efficiency for actual computational work.
Solution Approach 2:
The patent implements a mechanism to skip the multiplication operation entirely when both operands are detected as one. The detector circuit identifies these cases and directs the signal to bypass the multiplier circuit, effectively rushing through the unnecessary computation step to save energy while maintaining correct processing for non-trivial cases.
2Power
If the multiplier circuit is always active, then the processing speed is maintained, but the power consumption increases due to unnecessary operations
Solution Approach 1:
The patent introduces dynamic control of the multiplier circuit through the detector circuit and signal routing mechanism. The multiplier is activated only when necessary (when at least one operand is not one) and remains inactive when both inputs are one, creating a dynamic power management system that adapts to the actual computational requirements rather than maintaining constant activity.
Solution Approach 2:
The detector circuit acts as an intermediary between the input signals and the multiplier circuit. It detects the values of the inputs and uses this information to control whether the multiplier should be activated or bypassed, serving as a mediator that coordinates power management with processing requirements.
3Loss of energy
If the detector circuit and signal routing are added, then the power management is improved, but the device complexity increases
Solution Approach 1:
The patent merges the detection function and the control function into an integrated circuit design where the detector circuit and signal routing are combined with the existing multiplier architecture. This merging approach minimizes additional complexity by utilizing existing circuit elements for multiple purposes while achieving the desired power management functionality.
