Serial Interface Command Frame for Multi-Device Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing complexity of 5G communication systems requires efficient control of multiple peripheral devices within a short command transfer time, which existing technologies struggle to manage effectively, leading to potential malfunctions.
Innovation Solution
An electronic device with a processor connected to multiple peripheral devices via a serial interface, capable of transmitting a single command frame and data frames to control multiple devices simultaneously, using different voltage levels applied to pins to identify and control each device, thereby reducing side effects and enabling complex operations like CA combinations, MIMO, and 5G communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple peripheral devices are controlled through separate command transmissions, then each device can be controlled individually, but the command transfer time increases and system complexity increases
Solution Approach 1:
The patent combines multiple separate command transmissions into a single unified command frame that can control multiple peripheral devices simultaneously. The command frame includes a device identifier field that specifies which device(s) should execute the command, allowing one command to reach multiple devices through the serial interface without requiring separate transmissions for each device.
Solution Approach 2:
The serial interface controller is designed with multi-functionality to handle both single-device and multi-device control scenarios. The command frame structure is universal, supporting wildcard identifiers that can match multiple devices, and the controller can interpret and route a single command to appropriate target devices based on the identifier fields within the command frame.
2Reliability
If multiple peripheral devices are controlled through separate command transmissions, then each device receives dedicated control, but the system complexity and number of control elements increase
Solution Approach 1:
The patent merges multiple control channels into a single serial interface command stream. Instead of requiring separate control lines or interfaces for each peripheral device, the system uses one unified command frame that contains device identifiers and control data, reducing the number of control elements while maintaining reliable device-specific control.
Solution Approach 2:
The serial interface controller performs multiple functions: it parses command frames, identifies target devices based on identifier fields, routes commands to appropriate devices, and handles both single-device and multi-device scenarios. This multi-functional design reduces overall system complexity by consolidating control logic into a single controller rather than requiring dedicated control logic for each device.
3Loss of time
If a single command frame controls multiple peripheral devices, then command transfer time is reduced, but device identification and routing complexity increases
Solution Approach 1:
The command frame is segmented into distinct fields including device identifier fields, command type fields, and data fields. This segmentation allows the controller to systematically parse the command frame by extracting and processing each field in sequence, reducing parsing complexity compared to handling undifferentiated command streams.
Solution Approach 2:
The device identifier fields act as intermediaries between the command frame and the target peripheral devices. The controller uses these identifier fields to match commands with appropriate devices without requiring complex direct addressing logic, simplifying the routing process while enabling fast command delivery to multiple devices.
