1Productivity
If software optimization methods (multi-threading, lookup tables, cache) are used to improve program performance, then performance is improved to a certain extent, but performance cannot be further optimized due to design framework and language limitations
Solution Approach 1:
The system segments the simulation software into two independent processes: a host software process and a real-time kernel process. The real-time kernel process is configured as a daemon process that handles time-critical simulation tasks, while the host software handles high-level control and data processing. This segmentation allows each process to be optimized independently, with the real-time kernel able to achieve higher performance without being constrained by the host software's design framework and language limitations.
Solution Approach 2:
The patent introduces an inter-process communication mechanism as an intermediary between the host software and the real-time kernel. This communication interface enables the host software to control the real-time kernel process and retrieve simulation results without direct coupling, allowing the real-time kernel to operate with optimized performance while maintaining compatibility with the host software's framework.
2Productivity
If multiple threads are used to optimize program performance, then processing capability is improved, but system complexity and overhead increase
Solution Approach 1:
Instead of using multiple threads within a single process, the system segments functionality into separate processes. The real-time kernel process can utilize multiple threads internally if needed, but this is isolated from the host software, preventing thread management complexity from propagating to the overall system. This process-level segmentation simplifies the host software while maintaining processing capability.
3Speed
If lookup tables and cache are used to avoid iterative computation, then computation speed is improved, but memory usage increases
Solution Approach 1:
The patent extracts the computationally intensive simulation calculations from the host software and relocates them to the real-time kernel process. This allows the real-time kernel to implement optimized computation strategies (including lookup tables and cache) without being constrained by the host software's memory management limitations, while the host software maintains lower memory usage for control and data handling.
