Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing FPGA control systems face challenges in achieving variable data transmission with desired data rates and low latency while maintaining high efficiency, as current interfaces require significant effort and are not adaptable to different applications.
Innovation Solution
An adaptive serial interface is implemented between the FPGA and I/O modules, allowing configuration of a maximum number of registers and a common fixed register width, enabling efficient data transfer by only transmitting relevant data and dynamically adjusting bandwidth, thus achieving low latency and high data rates with minimal configuration effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a serial interface with configurable maximum number of registers and common fixed register width is implemented, then adaptability and ease of operation are improved, but device complexity increases
Solution Approach 1:
The patent implements a universal serial interface that can handle multiple FPGA applications with different data requirements through a common fixed register width and configurable maximum number of registers. This single interface design serves multiple functions across different applications without requiring separate custom interfaces for each case.
Solution Approach 2:
The interface allows dynamic configuration by changing parameters such as the maximum number of registers and enable signals for specific registers. This enables the same physical interface to adapt to different data transmission requirements by modifying its operational parameters rather than requiring hardware changes.
2Productivity
If only relevant data is transmitted by configuring enable signals for specific registers, then bandwidth utilization and productivity are improved, but device complexity increases
Solution Approach 1:
The patent extracts and transmits only the relevant data by configuring enable signals for specific registers that need to be transmitted. Instead of transmitting all register data, the system selectively extracts and transmits only the necessary portions, improving bandwidth utilization and transmission efficiency.
3Device complexity
If a fixed maximum number of registers is configured for all applications, then device complexity is reduced, but adaptability to different data transmission requirements deteriorates
Solution Approach 1:
The interface incorporates dynamic configuration capabilities where the maximum number of registers and enable signals can be adjusted based on the specific application requirements. This dynamic adaptability allows the same interface to optimize performance for different data rates and latency requirements without requiring multiple fixed interface designs.
