Dual-OS Embedded Resource Allocation for Multi-Core Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The low overall utilization rate of processing resources in multi-core processors due to most resources being in an idle state when services are processed by a combination of multi-core processors and acceleration hardware.
Innovation Solution
Implementing an embedded system with a resource dynamic allocation rule that allocates services to different operating systems based on service response speed, resource occupation rate, coupling degree, and importance, allowing services to be executed by processing resources dynamically allocated to different operating systems, thereby utilizing both multi-core processor and acceleration hardware resources efficiently.

1Speed
If services are processed by a combination of multi-core processors and specialized acceleration hardware, then services sensitive to response speed can be processed by acceleration hardware, but most processing resources of the multi-core processor remain idle resulting in low overall utilization rate
Solution Approach 1:
The multi-core processor is designed to perform multiple functions: it processes both services sensitive to response speed (traditionally handled by acceleration hardware) and services insensitive to response speed. By allocating different types of services to different cores based on their response speed requirements, the processor achieves multi-functionality, improving overall resource utilization while maintaining necessary response speeds for time-critical services.
Solution Approach 2:
The system implements dynamic service allocation where services are assigned to different cores based on real-time requirements for response speed. This dynamic allocation allows the system to adaptively optimize resource utilization by matching service characteristics with appropriate processing capabilities, rather than using a static division of labor between general-purpose processors and specialized acceleration hardware.
2Speed
If specialized acceleration hardware is used to process services sensitive to response speed, then response speed requirements are met, but device complexity increases and resource allocation becomes less flexible
Solution Approach 1:
Instead of adding specialized acceleration hardware for each type of service, the multi-core processor is designed to handle diverse service types universally. Each core can be dynamically assigned to process services based on their response speed requirements, eliminating the need for multiple specialized hardware components and reducing overall system complexity.
Solution Approach 2:
The patent merges the functions of general-purpose processing and specialized acceleration processing into a single multi-core processor system. By combining different processing capabilities within one integrated system and using dynamic allocation, it reduces the number of separate hardware components needed while maintaining the ability to meet response speed requirements for time-critical services.
