Serial Data Synchronization Using Non-Overlapping Load Signals
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data synchronization apparatuses imperfectly convert individual serial data signals into synchronized serial data signals due to overlapping load signals for operating Serial-to-Parallel (S/P) and Parallel-to-Serial (P/S) converters, leading to inefficient data processing and potential errors in biomedical signal processing systems.
Innovation Solution
A data synchronization apparatus that includes a signal conversion block converting individual serial digital signals into parallel digital signals using a non-overlapping synchronization load signal, a clock/load signal generator providing a reference load signal, a multiplexer for multiplexing synchronized signals, and a switch block to compensate for incomplete conversions, ensuring accurate synchronization without overlapping load signals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If load signals for S/P converter and P/S converter are generated in overlapped type, then device complexity is reduced, but data conversion accuracy deteriorates
Solution Approach 1:
The load signal generation is segmented into separate control signals for S/P converter and P/S converter. The synchronization load signal is divided into multiple phases, with each phase controlling one converter independently, preventing overlapping operations and ensuring accurate data conversion.
Solution Approach 2:
The synchronization load signal is generated in advance with predetermined timing relationships. The signal is prepared before conversion operations begin, with each phase sequentially enabling S/P conversion first, then P/S conversion, ensuring no overlap occurs during actual data processing.
2Productivity
If synchronization load signal overlaps with load signal, then conversion speed increases, but data synchronization reliability decreases
Solution Approach 1:
The synchronization load signal operates in periodic phases, sequentially activating S/P conversion and P/S conversion without overlap. Each converter is activated in its designated time window, ensuring reliable data synchronization while maintaining continuous conversion throughput through rhythmic operation cycles.
3Manufacturing precision
If non-overlapping synchronization load signal is used, then data conversion accuracy is improved, but device complexity increases
Solution Approach 1:
Multiple control functions are merged into a single synchronization load signal that simultaneously manages S/P converter and P/S converter operations. The signal combines phase information, enable/disable control, and timing coordination in one unified waveform, reducing the need for separate complex control circuits.
Solution Approach 2:
The synchronization load signal acts as an intermediary between the data source and the conversion circuits. It mediates the timing and coordination between S/P and P/S converters, ensuring accurate data transfer without requiring direct complex interconnections between all components.
