Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a single group of baseband signals is processed, then the processor architecture remains simple, but the device cannot handle multiple work tasks simultaneously
Solution Approach 1:
The processor is divided into multiple independent MAP groups (first MAP group, second MAP group, etc.), each capable of independently processing a group of baseband signals. This segmentation allows parallel processing of multiple signal groups while maintaining manageable complexity through modular design
Solution Approach 2:
Each MAP group is designed with universal functionality to process various types of signals including WiFi, GPS/BDS positioning, and 5G/6G modem signals. The common CPU groups provide backup processing capabilities that can be dynamically allocated to different MAP groups based on workload requirements
2Productivity
If multiple independent MAP groups are added to process multiple baseband signals, then parallel processing capability improves, but power consumption increases
Solution Approach 1:
The system implements dynamic power management where the master control system monitors workload requirements and dynamically adjusts the operational state of each MAP group. When parallel processing is needed, multiple MAP groups are activated; when processing demand decreases, MAP groups are powered down or placed in low-power mode, optimizing power consumption based on actual needs
Solution Approach 2:
Each MAP group includes its own CPU, GPU, audio processor, video encoder/decoder, and other processing units that can operate independently. This self-service capability allows individual MAP groups to handle their own processing tasks without requiring constant intervention from other groups, enabling more efficient power management
3Reliability
If common CPU groups are added as backup processing resources, then processing reliability improves, but device complexity increases
Solution Approach 1:
The master control system serves as an intermediary that manages the allocation and coordination between independent MAP groups and common CPU groups. It monitors the processing status of each MAP group and dynamically requisitions common CPU groups when processing limits are reached, providing a centralized control mechanism that simplifies the complexity of managing multiple processing resources
