Hybrid Memory Controller Soft Hard Logic Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory controller implementations in programmable logic devices (PLDs) face challenges in balancing customization and resource efficiency, as implementing logic in soft logic increases overhead, while hard logic implementations reduce customization and may not be compatible with multiple memory types or future standards.
Innovation Solution
A hybrid approach is adopted, where the memory controller is split between soft logic and hard logic components, with customizable logic for specific applications in soft logic and common, standardized logic for multiple memory types in hard logic, optimizing resource usage and compatibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the memory controller is implemented entirely in soft logic, then customization for specific applications is improved, but resource overhead increases and reduces availability for other functionality
Solution Approach 1:
The memory controller is divided into two distinct components: a hard logic component that handles common, standardized memory interface functions, and a soft logic component that provides application-specific customization. This segmentation allows each component to be optimized for its specific purpose while working together as an integrated system.
Solution Approach 2:
The patent combines hard logic and soft logic components into a unified memory controller system. The hard logic component provides efficient, resource-light handling of standardized functions, while the soft logic component adds customization capabilities, achieving both resource efficiency and adaptability.
2Device complexity
If the memory controller is implemented entirely in hard logic, then resource overhead is reduced, but customization for specific applications and compatibility with multiple memory types is reduced
Solution Approach 1:
The memory controller is divided into two distinct components: a hard logic component that handles common, standardized memory interface functions, and a soft logic component that provides application-specific customization. This segmentation allows each component to be optimized for its specific purpose while working together as an integrated system.
Solution Approach 2:
The hard logic component is designed to provide universal support for multiple memory types and standards through standardized interface logic. This allows the system to maintain broad compatibility while the soft logic component can be customized for specific applications, achieving both universality and specialization.
