Universal Microcode Image Segmentation Index
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Managing multiple microcode images for different device configurations in electronic devices, such as set-top boxes, is cumbersome and costly due to the need for extensive storage resources, as each device requires a unique permutation of images based on various parameters like media type, frequency band, and quality of service, leading to inefficient storage and management.
Innovation Solution
Creating a universal microcode image by identifying and storing only unique sections from multiple microcode images and using an index table to reconstruct the original images as needed, reducing storage requirements and simplifying management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If all possible permutations of microcode images are stored on each set-top box, then the device can properly initialize for any configuration, but the storage requirements and manufacturing costs increase significantly
Solution Approach 1:
The patent divides microcode images into multiple sections, where each section corresponds to specific device configuration parameters. Instead of storing complete microcode images for all permutations, the system stores only unique sections and uses an index table to assemble the appropriate sections at runtime based on the actual device configuration.
Solution Approach 2:
The patent creates a universal microcode image that can serve multiple device configurations. By using a single universal image with configurable sections selected via an index table, the system eliminates the need for separate microcode images for each device permutation, making one image file serve the function of multiple specialized images.
2Reliability
If multiple microcode images are stored for different device configurations, then proper initialization is ensured, but the management complexity and storage resources increase
Solution Approach 1:
The patent performs preliminary organization of microcode sections and creates an index table in advance that maps device configuration parameters to specific sections within the universal microcode image. This pre-organization eliminates the need for complex runtime management of multiple separate images, as the system only needs to look up and assemble sections based on the index table.
3Quantity of substance
If a single universal microcode image is used, then storage requirements are reduced, but the system must efficiently identify and assemble unique sections
Solution Approach 1:
The patent introduces an index table as an intermediary data structure that bridges the device configuration parameters and the sections within the universal microcode image. The index table contains mappings that allow the system to efficiently identify which sections to assemble based on the actual device configuration, without requiring complex analysis of the microcode image content itself.

AI summary
Systems and methods for creating universal microcode images and for reconstructing a microcode image from a universal microcode image are described in the present disclosure. One method, among others, comprises receiving a plurality of microcode images each configured to initialize hardware within an electronic device before the electronic device is booted up. The method also includes separating each microcode image into sections and comparing the sections to determine whether or not two or more sections contain identical code. The method also includes creating a universal microcode image from the sections that are unique.
