Embedded Storage Transfer Configuration for Mixed Firmware Compatibility

Solution Overview

Problem

Existing embedded memories face compatibility issues due to differences in firmware and specifications among multiple embedded multimedia cards, leading to increased power consumption and jitter, especially in large capacity products.

Innovation Solution

An embedded storage apparatus and method that aligns the transmission configuration of multiple storage devices based on their firmware versions to enable uniform read/write operations, reducing the need to frequently switch modes and speeds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the controller frequently switches different read/write modes and read/write speeds to accommodate different storage device specifications, then compatibility with multiple storage devices is improved, but power consumption increases and jitter occurs

Engineering Contradiction:

Improvecompatibility with multiple storage devicesVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The system performs firmware version detection and transmission configuration alignment during the initialization phase before actual read/write operations begin. By determining the common transfer configuration in advance (preliminarily), the controller avoids frequent switching during operation, thereby reducing power consumption and jitter while maintaining compatibility across multiple storage devices with different firmware versions

Inventive Principle:

Principle #10Preliminary action

2Adaptability or versatility

If the controller frequently switches different read/write modes and read/write speeds to accommodate different storage device specifications, then compatibility with multiple storage devices is improved, but jitter occurs

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The system performs firmware version detection and transmission configuration alignment during the initialization phase before actual read/write operations begin. By determining the common transfer configuration in advance (preliminarily), the controller avoids frequent switching during operation, thereby reducing power consumption and jitter while maintaining compatibility across multiple storage devices with different firmware versions
