Solution Overview
Problem
Current data processing technologies face inefficiencies in utilizing vector processing, as predicate flags controlling vector operations can lead to wasted resources and inefficient use of parallel processing due to inactive flags, which are not effectively monitored or optimized.
Innovation Solution
A data processing apparatus and method that incorporates vector processing circuitry to selectively apply vector operations based on predicate flags, along with generator circuitry to create instruction sample data indicating the state of these flags, allowing for performance monitoring and optimization of vector processing activities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If vector processing operations are applied to multiple data items simultaneously, then processing throughput is improved, but resources are wasted when predicate flags are inactive
Solution Approach 1:
The patent implements feedback by generating instruction sample data that captures the state of predicate flags during vector processing execution. This feedback mechanism allows the system to monitor whether predicate flags are active or inactive, enabling subsequent optimization decisions. The feedback loop closes by using this monitoring information to adjust vector processing operations, ensuring resources are only utilized when predicate flags indicate active processing should occur.
Solution Approach 2:
The system performs self-service by automatically monitoring its own predicate flag states through the generator circuitry. The vector processing apparatus monitors itself to identify when resources are being wasted due to inactive predicate flags, and can autonomously adjust its operation to prevent such waste without external intervention.
2Adaptability or versatility
If predicate flags are used to control vector operations, then processing selectivity is improved, but monitoring and optimization complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism - the generator circuitry - that mediates between the vector processing operations and the monitoring function. This intermediary captures instruction sample data representing predicate flag states, simplifying the monitoring task by providing processed, ready-to-analyze data rather than requiring direct complex monitoring of internal processor states.
3Productivity
If instruction sample data is generated for monitoring, then processing optimization is enabled, but additional processing overhead is introduced
Solution Approach 1:
The system applies partial action by generating instruction sample data selectively rather than continuously. The generator circuitry captures predicate flag states for selected vector processing instructions, monitoring only when necessary to identify optimization opportunities. This partial monitoring approach enables efficiency improvements while minimizing the time overhead associated with continuous comprehensive monitoring.
