Boot Instruction Segmentation During RF Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing computing devices, particularly wireless communication devices like earbuds and headsets, face challenges in reducing boot time due to the serial execution of boot instruction downloading and RF calibration processes, which can be lengthy and inefficient.
Innovation Solution
The boot instructions are divided into a start-up boot instruction segment and a mission-mode boot instruction segment, where the start-up segment is downloaded and executed before RF calibration, and the mission-mode segment is downloaded and executed in parallel with RF calibration, optimizing the boot process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If boot instructions are executed sequentially before RF calibration, then system stability is maintained, but boot time increases
Solution Approach 1:
The boot instructions are segmented into two distinct segments: a first boot instruction segment that must be executed before RF calibration, and a second boot instruction segment that can be executed during or after RF calibration. This segmentation allows parallel execution of different boot tasks, reducing overall boot time while maintaining system stability through structured execution phases.
2Loss of time
If RF calibration is performed before boot instructions are downloaded, then wireless communication readiness is ensured, but boot time increases
Solution Approach 1:
The first boot instruction segment performs preliminary actions by downloading and executing critical boot instructions before the RF calibration process begins. This ensures that essential system initialization is complete while the RF calibration can proceed independently in the background, allowing the second boot instruction segment to be downloaded during calibration without delaying wireless communication readiness.
3Loss of time
If all boot instructions are downloaded before RF calibration, then instruction execution order is simplified, but boot time increases
Solution Approach 1:
The boot instruction execution is made dynamic by allowing the second boot instruction segment to be downloaded and executed during the RF calibration process rather than requiring all instructions to be downloaded beforehand. This dynamic approach optimizes boot time by overlapping instruction download with calibration execution, while the structured segmentation maintains clear execution order through defined phases.

AI summary
Systems and methods for reducing boot time in a computer system divide the boot instructions into a start-up boot instruction segment and a mission-mode boot instruction segment. The start-up boot instruction segment is downloaded from persistent memory of the computer system to a random access memory (RAM) of the computer system and executed prior to a radio frequency (RF) analog (RFA) module of the computer system perform an RF calibration process that calibrates the RFA module to perform a wireless communication protocol. During the RF calibration process, the mission-mode boot instruction segment is downloaded from persistent memory to RAM and executed. Downloading the mission-mode boot instruction segment during the RF calibration process greatly reduces the overall amount of time required to boot the computer system.
