Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory systems struggle to efficiently manage diverse memory requirements of different processing units with varying performance characteristics, leading to suboptimal performance and resource allocation.
Innovation Solution
Implementing a unified memory system with direct and cross connections between memory clients and sections, allowing for high-performance access to associated memory sections and flexible access to all sections, while maintaining a single contiguous physical address space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If a unified memory system with direct and cross connections is implemented, then memory access performance is improved, but device complexity increases
Solution Approach 1:
The memory system is segmented into multiple memory sections (first memory section, second memory section, etc.) that can be independently accessed. Each memory section can be coupled to one or more memory clients through direct connections or cross connections, allowing parallel access operations and improving overall memory access performance while distributing system complexity across modular components
Solution Approach 2:
The patent introduces a dimensional aspect to memory access by implementing both direct connections (within same memory section) and cross connections (between different memory sections). This creates a multi-dimensional access topology where memory clients can access memory through different pathways, enhancing performance while managing complexity through structured connection patterns
2Productivity
If multiple memory clients access different memory sections with varying performance characteristics, then resource allocation efficiency is improved, but system complexity increases
Solution Approach 1:
Different memory sections are assigned different performance characteristics tailored to specific memory clients' needs. Each memory section can have optimized access times, bandwidth, or capacity suited to its associated memory client's requirements, improving resource allocation efficiency while maintaining manageable system complexity through localized optimization rather than global redesign
3Speed
If direct memory connections are used for high-performance access, then access speed is improved, but flexibility in accessing all memory sections is reduced
Solution Approach 1:
The memory system implements a universal access architecture where memory clients can access any memory section through either direct connections (for high-speed access to associated sections) or cross connections (for flexible access to all sections). This multi-functional connection structure allows the system to provide both high-performance dedicated access and flexible universal access, resolving the contradiction between speed and adaptability
Data Source
AI summary
A technique for operating a memory system is disclosed. The technique includes performing a first request, by a first memory client, to access data at a first memory address, wherein the first memory address refers to data in a first memory section that is coupled to the first memory client via a direct memory connection; servicing the first request via the direct memory connection; performing a second request, by the first client, to access data at a second memory address, wherein the second memory address refers to data in a second memory section that is coupled to the first client via a cross connection; and servicing the second request via the cross connection.
