Handshake Signal Splitting Circuit for Flexible Multi-Module Data Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital circuit designs limit flexibility and application scenarios by requiring multiple back-end modules to simultaneously receive data from a front-end module, reducing the flexibility of data calculation and limiting the use cases.
Innovation Solution
A circuit and method that allows multiple back-end modules to receive data simultaneously by using a first and second level processing module and logic control circuits to control the handshake process, ensuring time-divided data reception, with each logic control circuit corresponding to a back-end module, allowing the circuit to output levels that prevent further data reception until all modules have completed the handshake.

Engineering Contradiction Analysis
1Reliability
If multiple back-end modules simultaneously receive data from a front-end module using traditional handshake signal splitting circuits, then data transmission reliability is ensured, but flexibility of data calculation and application scenarios are reduced
Solution Approach 1:
The patent segments the handshake signal control by introducing independent logic control circuits for each back-end module. Each logic control circuit independently manages the handshake signal between the front-end module and a specific back-end module, allowing selective and flexible data reception. This segmentation enables different back-end modules to receive data at different times or in different configurations while maintaining reliable handshake protocols for each individual connection.
2Productivity
If traditional handshake signal splitting circuits are used, then data transmission is controlled, but multiple back-end modules can only simultaneously receive data which limits application scenarios
Solution Approach 1:
The patent introduces dynamic control capability through logic control circuits that can independently manage handshake signals for different back-end modules. This dynamic control allows the system to adaptively configure which back-end modules receive data at different times, supporting both simultaneous and sequential reception modes. The dynamic nature of the control enables flexible adaptation to various application scenarios including parallel processing, pipeline operations, and selective data distribution.
3Adaptability or versatility
If independent control for each back-end module is implemented, then flexibility and application scenarios are expanded, but circuit complexity increases
Solution Approach 1:
The patent employs a modular copying approach where a standardized logic control circuit design is replicated for each back-end module. Each logic control circuit follows the same structural template with standardized inputs (handshake signal, valid signal) and outputs (feedback signal, level output), making the circuit design reusable and systematic. This copying strategy manages complexity by providing a predictable, repeatable pattern rather than requiring unique complex designs for each module.
Solution Approach 2:
The logic control circuits are designed with universal functionality to handle multiple operations including data reception enablement, feedback signal generation, and level output for coordinating multiple back-end modules. Each logic control circuit can operate independently but also coordinates with others through shared signals, providing multi-functional capability that reduces the need for separate specialized circuits for different operations.

AI summary
Disclosed are a circuit, method, apparatus and device of splitting a handshake signal, and a non-volatile readable storage medium. Logic control circuits can only control, when a valid signal output end of a front-end module outputs a first level and feedback signal output ends output a second level, the back-end modules corresponding to the logic control circuits to complete a current handshake, and output, before the front-end module completes the current handshake, a level opposite to the first level to valid signal receiving ends of the back-end modules corresponding to the logic control circuits, and the second level to a first level processing module, such that the first level processing module outputs the second level after all the back-end modules complete the current handshake, and thus the front-end module completes the current handshake.
