Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bus systems require multiple interfaces and wires to handle different data formats like bitstream and digital word data, leading to increased costs, space requirements, and power consumption, especially when used with external devices.
Innovation Solution
The unified bus communication protocol provides a single interface that can handle bitstream, digital word, and control data using a reduced number of wires, allowing for multiplexing of digital word data with bitstream data and embedding control data within the multiplexed bitstream format, thereby eliminating the need for additional interfaces and reducing the number of terminals and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple interfaces and wires are used to handle different data formats (bitstream and digital word data), then data format compatibility is improved, but device complexity, space requirements, and power consumption increase
Solution Approach 1:
The patent implements a universal bus interface that can handle multiple data formats (bitstream, digital word, and control data) through a single interface. The system uses a unified protocol that multiplexes different data types on the same physical bus, eliminating the need for separate interfaces for each data format while maintaining full compatibility with legacy systems.
Solution Approach 2:
The patent combines multiple data transmission functions into a single bus system. Control data is embedded within the multiplexed bitstream format, and digital word data is multiplexed with bitstream data on the same physical wires. This merging of functions reduces the number of terminals and simplifies the overall system architecture.
2Adaptability or versatility
If multiple interfaces and wires are used to handle different data formats, then data format compatibility is improved, but power consumption increases
Solution Approach 1:
The universal bus interface handles multiple data formats through a single powered connection, eliminating the need for multiple powered interfaces. The system achieves power efficiency by using one unified communication protocol that can transmit bitstream, digital word, and control data through the same physical medium, thereby reducing overall power consumption.
Solution Approach 2:
The patent merges control data transmission with the existing bitstream data transmission by embedding control information within the multiplexed format. This eliminates separate control signal wires and their associated power requirements, reducing total power consumption while maintaining full control functionality.
3Device complexity
If a single interface is used to handle multiple data formats through multiplexing, then device complexity is reduced, but data transmission reliability may worsen
Solution Approach 1:
The patent segments data transmission into synchronized frames with distinct fields for different data types. Each frame contains synchronization patterns and clearly demarcated sections for control data and payload data. This structured segmentation allows the receiver to reliably distinguish and process different data formats without confusion, even though they share the same physical interface.
Solution Approach 2:
The system incorporates synchronization mechanisms and error detection capabilities that provide feedback to ensure reliable data transmission. The synchronization patterns enable the receiver to confirm proper frame alignment and data integrity, maintaining high reliability despite the use of a single multiplexed interface.

AI summary
Various embodiments are described herein related to techniques for synchronizing a slave device to a master device that communicates using a unified bus communication protocol or some aspect thereof. In one example, the method may comprise assuming a first mode of operation for the unified bus communication protocol; searching for a synchronization pattern at one or more locations in transmitted data according to the first mode of operation; obtaining synchronization when the located synchronization pattern is verified according to at least one synchronization rule for the mode of operation; and if synchronization is not obtained based on the assumed first mode of operation, a second mode of operation for the unified bus communication protocol is assumed and the searching and obtaining acts are carried out on the transmitted data according to the second mode of operation.
