Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The performance of electronic systems, particularly those with field programmable gate arrays (FPGAs), is hindered by resource allocation inefficiencies, leading to decreased system speed and increased power consumption due to the allocation of resources to unused function blocks.
Innovation Solution

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple function blocks share limited FPGA resources, then resource utilization increases, but system speed decreases and power consumption increases due to allocation of resources to unused function blocks
Solution Approach 1:
The patent implements dynamic reconfiguration of FPGA resources by loading only the necessary function blocks into the FPGA based on runtime requirements. The system uses a configuration memory to store multiple function block configurations and selectively loads them into the FPGA fabric as needed, transforming the static resource allocation into a dynamic one. This allows the system to maintain high resource utilization for active functions while keeping unused resources unavailable, thereby preserving system speed and reducing power consumption.
Solution Approach 2:
The patent divides the FPGA resource pool into multiple separable function blocks that can be independently loaded and unloaded. Each function block is configured separately in the configuration memory and can be selectively instantiated in the FPGA fabric. This segmentation allows the system to load only the specific function blocks required for current operations, preventing resource contention and maintaining optimal performance for active functions while avoiding the overhead of maintaining all possible functions simultaneously.
2Adaptability or versatility
If multiple function blocks share limited FPGA resources, then resource utilization increases, but power consumption increases due to allocation of resources to unused function blocks
Solution Approach 1:
The system dynamically controls power consumption by selectively activating only the function blocks that are currently needed. The configuration memory stores multiple function block configurations, and the system controller loads only the relevant configurations into the FPGA fabric based on runtime requirements. Unused function blocks remain unloaded and do not consume FPGA resources or power, thereby resolving the contradiction between high resource utilization and low power consumption.
3Productivity
If code is synthesized from high level language to hardware description language and IP blocks are designed based on access results, then resource allocation efficiency improves, but processing complexity increases
Solution Approach 1:
The system implements automated code synthesis and IP block design through integrated processing circuitry that performs high-level language to hardware description language compilation, circuit design, and configuration generation automatically. The processing circuitry analyzes access patterns and runtime requirements, then autonomously synthesizes the appropriate hardware configurations without requiring manual intervention. This self-service approach handles the processing complexity internally while presenting a simplified interface to users, thereby improving resource allocation efficiency without burdening the user with complex processing tasks.
