Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If hypervisor capabilities are implemented on fixed hardware resources, then virtual machines can be created with different operating systems and hardware peripherals, but hardware vulnerabilities and performance degradation occur due to fixed circuitry
Solution Approach 1:
The patent applies dynamics by replacing fixed hardware resources with reconfigurable hardware devices that can dynamically change their physical characteristics and circuitry configuration. This allows the hardware to adapt to different virtual machine requirements while eliminating vulnerabilities associated with fixed circuitry, as the reconfigurable nature enables continuous updates and reconfiguration without physical replacement.
Solution Approach 2:
The patent implements parameter changes by enabling the reconfigurable hardware devices to modify their physical characteristics and operational parameters. This allows the hardware resources to be reconfigured for different virtualization needs, changing their properties dynamically rather than being fixed, thereby improving both adaptability and security through configurable updates.
2Productivity
If main processors and hardware resources are used for virtualization, then general purpose computing is enabled, but performance degradation occurs through hardware bugs and component aging
Solution Approach 1:
The patent applies copying by creating virtual instances of hardware resources through reconfigurable hardware devices. Instead of relying on physical hardware that degrades over time, the system creates configurable virtual representations that can be instantiated, cloned, and replaced without physical wear, thereby maintaining high performance and reliability in virtualized environments.
Solution Approach 2:
The patent uses dynamics to enable the hardware resources to be reconfigured and reassigned dynamically. This allows the system to optimize performance for specific virtualization workloads by reconfiguring the reconfigurable hardware devices, avoiding the performance degradation inherent in fixed hardware that cannot adapt to changing computational demands.
3Stability of the object's composition
If hardware resources are made permanent and fixed, then physical stability is maintained, but security vulnerabilities arise from un-patchable hardware flaws
Solution Approach 1:
The patent applies dynamics by making the hardware resources changeable rather than fixed. The reconfigurable hardware devices can be dynamically updated and reconfigured, allowing security patches and updates to be applied without replacing physical hardware. This maintains stability through continuous operation while eliminating the un-patchable vulnerability of fixed hardware.
Solution Approach 2:
The patent implements parameter changes that enable the hardware to be reconfigured and updated. By changing the configuration parameters and circuitry of the reconfigurable hardware devices, the system can apply security updates and patches while maintaining operational stability, thereby removing the harmful effect of un-patchable hardware flaws.
4Adaptability or versatility
If reconfigurable hardware devices are used to instantiate virtual System-on-Chip instances, then dynamic reconfiguration and security are enhanced, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the reconfigurable hardware into modular components and instances. Instead of a single complex reconfigurable system, the hardware is segmented into multiple virtual System-on-Chip instances that can be independently configured and managed. This reduces the complexity of individual components while maintaining overall reconfigurability and adaptability.
Solution Approach 2:
The patent uses nesting by placing virtual instances within the reconfigurable hardware framework. The virtual System-on-Chip instances are nested within the reconfigurable hardware devices, allowing multiple levels of virtualization and configuration. This nested structure manages complexity by organizing reconfigurable resources in hierarchical layers, making the system more manageable despite the advanced reconfigurability.
