Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If Simultaneous Multi-Threading (SMT) is used to interleave instructions from multiple software threads, then processor underutilization is eliminated when threads are stalled, but hardware underutilization remains unaddressed
Solution Approach 1:
The system dynamically reconfigures processing elements at runtime to change their functional characteristics. Processing elements can be dynamically allocated to different tasks and can change their operational mode based on workload requirements, enabling both high processor utilization and hardware adaptability simultaneously
Solution Approach 2:
Processing elements are designed to perform multiple functions by dynamically reconfiguring their hardware resources. A single processing element can serve different computational roles depending on the task requirements, eliminating hardware underutilization while maintaining SMT benefits
2Productivity
If Application Specific Configurable hardware (ASC) is designed to meet performance requirements, then performance constraints are satisfied, but system complexity and design difficulty increase
Solution Approach 1:
The system is divided into multiple identical processing elements that can be independently configured and managed. Each processing element is a standardized unit that can be individually allocated to different tasks, reducing overall system design complexity while maintaining high performance through parallel processing
Solution Approach 2:
The system provides dynamic reconfiguration capabilities that allow processing elements to be assigned different functions at runtime without requiring complex static design. This dynamic approach simplifies the design process while enabling performance optimization for various applications
3Adaptability or versatility
If processing resources are increased to handle varying processing requirements, then adaptability to changing requirements improves, but power consumption and area increase
Solution Approach 1:
The system dynamically activates or deactivates processing elements based on current workload demands. When processing requirements are low, fewer elements are active, reducing power consumption. When demands increase, additional elements are activated, providing adaptability without permanently increasing power usage
Solution Approach 2:
A small number of multi-functional processing elements replace a large number of specialized elements. Each element can adapt to different computational tasks, providing high adaptability while using fewer physical components, thereby reducing power consumption and area
