Distributed BIOS Runtime for Secure Cross-Processor Battery Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information handling systems lack a processor environment agnostic method for securely communicating between ACPI source language (ASL) and audio digital signal processing (ADSP) firmware, which is essential for seamless interaction between embedded controllers and operating system drivers across different processor architectures, particularly for battery charging and power management.
Innovation Solution
A processor environment agnostic information handling system audio digital signal processing trusted communication operation is implemented, utilizing a secure trust zone interface (STZI) and a unified system management BIOS (SMBIOS) table to provide a seamless and secure interface between embedded controllers and operating system drivers, enabling module-specific interactions and real-time monitoring of battery attributes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If processor environment specific firmware communication methods are used, then communication reliability for specific architectures is improved, but system adaptability across different processor architectures deteriorates
Solution Approach 1:
The patent introduces a processor environment agnostic unified runtime service as an intermediary layer between the ACPI source language (ASL) and audio digital signal processing (ADSP) firmware and the operating system drivers. This mediator translates and standardizes communication protocols, allowing secure firmware communication across different processor architectures (x86, ARM, RISC-V) without requiring architecture-specific communication methods, thus resolving the contradiction between reliability and adaptability
Solution Approach 2:
The unified runtime service provides universal communication functionality that works across multiple processor environments. It implements a standardized interface that can handle firmware communication for various architectures through a single unified mechanism, enabling the system to adapt to different processor types while maintaining reliable communication through consistent protocols
2Adaptability or versatility
If processor environment agnostic unified runtime communication operation is implemented, then system adaptability across processor architectures is improved, but device complexity increases
Solution Approach 1:
The patent segments the firmware communication functionality into distinct components: the processor environment agnostic unified runtime service handles high-level standardized communication, while lower-level architecture-specific details are encapsulated within the service implementation. This segmentation allows the unified interface to remain simple and adaptable while managing complexity internally through modular design
