Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current interrupt request signal processing systems struggle to handle peripheral devices with varying interrupt signal formats, leading to limited compatibility and reduced processing efficiency due to the inability to accurately identify and process interrupt requests from all types of peripheral devices.
Innovation Solution
An interrupt request signal conversion system that includes an interrupt request signal converter generating converted interrupt request signals with multiple identification bits, allowing the system to differentiate between interrupt requests from different peripheral devices within a predetermined time range, and sends these signals to the processor's interface module for processing, thereby expanding compatibility and increasing processing speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the processor uses a fixed interrupt signal format, then the processing logic is simple, but the compatibility with different peripheral devices is limited
Solution Approach 1:
The patent introduces an interrupt signal conversion system as an intermediary component between peripheral devices and the processor. This conversion system receives interrupt signals from various peripheral devices with different formats, converts them into a standardized format, and then sends them to the processor. This mediator approach enables the processor to maintain simple processing logic while achieving broad compatibility with different peripheral devices through the format-unifying conversion layer.
Solution Approach 2:
The interrupt signal conversion system dynamically changes the format parameters of interrupt signals based on the source device. It detects the interrupt signal format from different peripheral devices and transforms them into a unified standard format that the processor can handle. This parameter transformation capability allows the system to adapt to various peripheral devices without changing the processor's internal processing logic.
2Productivity
If the processor processes interrupt requests from all peripheral devices directly, then the response time is fast, but the processing efficiency decreases due to format differentiation overhead
Solution Approach 1:
The interrupt signal conversion system performs preliminary action by pre-converting interrupt signals from various formats into a unified standard format before they reach the processor. This advance format unification eliminates the need for the processor to perform format differentiation and conversion during interrupt handling, thereby improving processing efficiency without adding response time overhead. The conversion happens proactively in the signal path rather than during the critical processor response phase.
3Adaptability or versatility
If the system uses multiple interrupt signal formats for different devices, then the compatibility is improved, but the difficulty of detecting and measuring interrupt sources increases
Solution Approach 1:
The conversion system acts as an intermediary that not only converts signal formats but also maintains and translates interrupt source identification information. It detects the source device from various format signals, performs the format conversion, and preserves the source identification in a standardized form that the processor can easily interpret. This mediator function simplifies interrupt source detection while maintaining compatibility with multiple device types.
Solution Approach 2:
The interrupt signal conversion system implements a universal identification mechanism that works across all peripheral device types. It provides a multi-functional capability to detect, convert, and identify interrupt sources from various devices using a unified approach. This universal identification system allows the processor to determine the interrupt source regardless of the original device format, thereby reducing the difficulty of detecting and measuring interrupt sources while maintaining broad device compatibility.

AI summary
An interrupt request signal conversion system includes an interrupt request signal converter configured to generate one or more converted interrupt request signals based on one or more signals received from one or more peripheral devices, and a signal output terminal configured to send the one or more converted interrupt request signals to an interface module of a processor during operation. Each of the one or more converted interrupt request signals includes a plurality of interrupt identification bits each used to identify, based on a first level and a second level different from the first level, whether a signal received from a corresponding one of the one or more peripheral devices within a predetermined time range includes a peripheral interrupt request signal.
