Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for initializing multiple electronic devices connected to a single host apparatus are time-consuming due to the long duration required for device control.
Innovation Solution
A semiconductor system that initializes multiple electronic devices in groups by using a host apparatus to synchronize and assign unique device IDs, allowing for simultaneous or grouped initialization within power supply constraints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional initialization methods are used for multiple electronic devices, then each device can be initialized individually, but the total initialization time becomes very long
Solution Approach 1:
The patent combines multiple device initializations into a single broadcast packet that is transmitted once to all devices simultaneously. Instead of sending separate initialization packets to each device sequentially, the host apparatus creates one packet containing initialization data for multiple devices, which are all initialized in parallel, dramatically reducing total initialization time.
Solution Approach 2:
The patent segments the initialization data within the broadcast packet into device-specific portions using device ID fields. Each device identifies its own initialization data by matching its device ID with the packet contents, allowing simultaneous initialization of multiple devices while maintaining individualized configuration for each device type.
2Loss of time
If multiple devices are initialized simultaneously using broadcast packets, then initialization time is reduced, but power consumption increases beyond available supply
Solution Approach 1:
The patent dynamically adjusts the number of devices initialized in each broadcast packet based on available power supply. The host apparatus monitors power availability and adapts the initialization strategy accordingly, dividing devices into groups that can be simultaneously initialized within power constraints, thereby balancing speed and power consumption.
Solution Approach 2:
The patent uses periodic batched initialization where devices are initialized in successive groups rather than all at once. Each broadcast packet initializes a subset of devices, and the host waits for power availability between batches, creating a periodic initialization pattern that respects power supply limitations while still achieving faster overall initialization than sequential methods.
3Use of energy by moving object
If sequential initialization is performed for each device, then power consumption remains within limits, but the initialization process becomes extremely time-consuming
Solution Approach 1:
The patent merges multiple sequential initialization operations into parallel execution by using broadcast packets that reach multiple devices simultaneously. This combining approach increases initialization throughput from sequential to parallel processing while managing power through intelligent packet construction that includes only devices capable of being initialized within available power budgets.
