Engineering Contradiction Analysis
1Reliability
If unique control commands for each modem type are implemented, then radio applications can control the modem accurately, but it becomes impractical to operate radio applications across different modem chips without extensive optimization efforts
Solution Approach 1:
The patent introduces a baseband accelerator as an intermediary layer between the radio application and the modem chip. This baseband accelerator provides a standardized interface that translates generic radio application commands into modem-specific control commands, enabling cross-modem compatibility while maintaining accurate modem control through the translation layer
Solution Approach 2:
The patent segments the radio application execution environment into separate components: a standardized baseband accelerator layer and the underlying modem-specific hardware layer. This segmentation allows the radio application to operate independently of modem variations by isolating the compatibility layer from the hardware-specific layer
2Manufacturing precision
If different execution files for each modem are manufactured, then radio applications can be optimized for specific modem performance, but a huge workforce is required and it is virtually impossible for a radio application to be operated in all terminals
Solution Approach 1:
The baseband accelerator is designed with universal functionality that can adapt to multiple modem types through configuration rather than requiring separate execution files. The single baseband accelerator implementation can serve different modem chips by loading appropriate configuration parameters, eliminating the need for multiple specialized versions
3Productivity
If radio applications are optimized for each modem hardware, then performance can be maximized for that specific modem, but the optimization process becomes extremely complex and time-consuming
Solution Approach 1:
The baseband accelerator is pre-configured with standardized interfaces and translation capabilities before deployment. This preliminary setup eliminates the need for time-consuming optimization processes for each new modem, as the accelerator is already prepared to handle various modem types through its pre-established translation framework
