PCI Express Interface Exchange for Automatic Memory Layout Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The development of complex systems with multiple data processing units using PCI Express communication is complicated by the need for manual exchange of configuration files to adapt memory layouts and interfaces, leading to inefficiencies and increased time consumption.
Innovation Solution
A method for exchanging interface information between communication partners via PCI Express, involving ascertaining an interface definition, creating a serialized form, and automatically configuring the second communication partner using this definition to facilitate dynamic adaptation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual exchange of configuration files is used to adapt memory layouts and interfaces, then communication between data processing units via PCI Express is enabled, but the development process becomes extremely complex and time-consuming
Solution Approach 1:
The system enables self-service by allowing the first communication partner to automatically provide its interface definition to the second communication partner. The second communication partner then automatically configures itself based on this definition, eliminating the need for manual configuration file exchange and reducing development complexity while maintaining adaptability.
Solution Approach 2:
The interface definition is ascertained and made available in advance before the second communication partner needs to access the memory areas. This preliminary preparation of interface information allows the second communication partner to automatically configure itself without requiring manual intervention during the development process.
2Reliability
If manual exchange of configuration files is used to adapt interfaces, then communication compatibility is achieved, but the development time increases significantly
Solution Approach 1:
The automatic configuration process allows the second communication partner to self-configure based on the interface definition provided by the first communication partner. This eliminates manual configuration file exchange, maintaining communication compatibility while dramatically reducing the time required for development activities.
Solution Approach 2:
The interface definition is prepared in advance by the first communication partner, containing all necessary information about memory areas and access parameters. This preliminary action ensures that when the second communication partner needs to access these areas, it can immediately configure itself without time-consuming manual processes.
3Speed
If direct memory access via PCI Express is implemented, then high communication speeds are achieved, but the requirement for precise memory management knowledge increases system complexity
Solution Approach 1:
The interface definition acts as an intermediary that bridges the first and second communication partners. It contains all the necessary information about memory areas, access parameters, and layout details, allowing the second communication partner to correctly access memory without requiring complex manual configuration or deep knowledge of the first partner's internal memory management.

AI summary
A method for exchanging interface information between different communication partners for the communication of the communication partners via PCI Express. The method includes: a) ascertaining an interface definition, which describes memory areas and an internal memory layout of a first communication partner which a second communication partner is to access to read and/or write data; b) creating a serialized form of the interface definition ascertained in step a); c) providing the serialized form of the interface definition created in step b) to the second communication partner; and d) automatically configuring the second communication partner with the transmitted interface definition for the communication between the communication partners.
