Solution Overview

Problem

The challenge lies in ensuring operational compatibility between older driver modules and newer network interface hardware, particularly in computer systems, where logistics and development schedule mismatches often lead to compatibility issues, especially for network interface hardware that requires updated drivers for efficient data transfer.

Innovation Solution

The implementation of firmware abstraction of hardware data queues, which converts and manipulates data descriptors to mask differences between older driver modules and evolving network interface hardware, enabling forward compatibility and allowing older drivers to work with newer hardware versions, including the ability to download updates through the network interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If firmware abstraction is implemented to mask hardware differences, then forward compatibility between older drivers and newer hardware is improved, but device complexity increases due to additional abstraction layers

Engineering Contradiction:
Improveforward compatibilityVSAvoidfirmware abstraction layer
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a firmware abstraction layer that acts as an intermediary between the driver module and network interface hardware. This firmware layer translates driver requests into hardware-specific operations, allowing older drivers to work with newer hardware without direct modification. The firmware masks hardware differences by presenting a standardized interface to the driver while handling the complexity of hardware variations internally.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system is segmented into distinct layers: the driver module layer, the firmware abstraction layer, and the hardware layer. This segmentation allows each layer to be developed and maintained independently. The firmware layer specifically handles the compatibility translation, separating the driver from hardware-specific complexities and enabling forward compatibility without requiring driver updates.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If data descriptors are converted and manipulated to mask hardware differences, then compatibility is improved, but processing time and computational resources increase

Engineering Contradiction:
ImprovecompatibilityVSAvoiddescriptor conversion time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The firmware performs preliminary conversion of data descriptors from the driver's format into the hardware's expected format before the actual data transfer operation. By pre-processing the descriptors and preparing them in advance, the system avoids time-critical conversions during active data transmission, thereby minimizing the impact on processing time while maintaining compatibility.

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If firmware abstraction is used to enable older drivers with newer hardware, then forward compatibility is achieved, but resource requirements and processing overhead increase

Engineering Contradiction:
Improveforward compatibilityVSAvoidfirmware processing energy
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The firmware abstraction layer is designed to efficiently manage its own processing tasks and minimize unnecessary operations. It intelligently determines when conversion is needed and optimizes the conversion process to reduce computational overhead and energy consumption. The system avoids redundant processing by caching descriptor formats and reusing conversion templates for similar hardware variations.

Inventive Principle:
Principle #25Self-service
