Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a dedicated GPU debugging core is added to the GPU core, then debugging capability is improved, but device complexity increases

Engineering Contradiction:
Improvedebugging capabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The debugging functionality is segmented into a separate dedicated GPU debugging core within the GPU core portion, distinct from the main GPU computing cores. This segmentation allows the debugging functions to be independently implemented and managed, improving debugging capability without significantly impacting the overall device complexity.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If multiple debugging contexts are supported, then versatility is improved, but ease of operation deteriorates

Engineering Contradiction:
Improvedebugging versatilityVSAvoiddebugging ease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The dedicated GPU debugging core is designed with multi-functional capabilities to handle various debugging contexts including CPU-GPU interactions, GPU-only debugging, and system-level crash analysis. By integrating multiple debugging functions within a single dedicated core, the system achieves versatile debugging support while maintaining ease of operation through unified access mechanisms.

Inventive Principle:
Principle #6Universality (Multi-functionality)
