Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If customized signal processing methods are implemented for each hardware platform, then processing reliability is improved, but device complexity and development time increase
Solution Approach 1:
The patent implements a unified processing framework that can operate in multiple modes (first processing mode using look-up tables, second processing mode using direct computation) to handle different wireless communication protocols. This multi-functional approach allows the same hardware platform to reliably process various protocols without requiring customized hardware designs for each protocol, thereby reducing device complexity while maintaining processing reliability.
2Manufacturing precision
If hardware-specific customized designs are used, then processing precision is improved, but adaptability to different protocols deteriorates
Solution Approach 1:
The patent employs dynamic mode selection where the processing mode is determined based on the specific wireless communication protocol being used. The system can switch between first processing mode (using look-up tables for high precision) and second processing mode (using direct computation for flexibility). This dynamic adaptation allows the system to maintain high processing precision when needed while simultaneously adapting to different protocols, resolving the contradiction between precision and adaptability.
3Productivity
If more MAC units and MLUs are deployed, then processing capability is improved, but power consumption increases
Solution Approach 1:
The patent changes the operational parameters of the processing units by implementing two distinct processing modes. The first mode uses pre-computed look-up tables stored in memory, reducing real-time computational requirements and power consumption. The second mode uses direct computation with coefficient data. The system dynamically selects the appropriate mode based on protocol requirements, thereby optimizing the balance between processing capability and power consumption without requiring additional hardware units.

AI summary
Examples described herein include systems and methods which include wireless devices and systems with examples of mixing input data delayed versions of at least a portion of the respective processing results with coefficient data specific to a processing mode selection. For example, a computing system with processing units may mix the input data delayed versions of respective outputs of various layers of multiplication/accumulation processing units (MAC units) for a transmission in a radio frequency (RF) wireless domain with the coefficient data to generate output data that is representative of the transmission being processed according to a wireless processing mode selection. In another example, such mixing input data with delayed versions of processing results may be to receive and process noisy wireless input data. Examples of systems and methods described herein may facilitate the processing of data for 5G wireless communications in a power-efficient and time-efficient manner.
