Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If radar data is processed using traditional radar processing pipelines, then the processing is specialized for radar signals, but the system cannot leverage high processing power and flexibility of multi-vector processors and has higher costs
Solution Approach 1:
The patent applies universality by converting radar data into camera interface frames that can be processed by vision processing units, which are originally designed for image processing. This allows a single multi-vector processor to handle both camera and radar data processing tasks, eliminating the need for separate specialized radar processing hardware and achieving cost-effectiveness while maintaining high processing power.
2Adaptability or versatility
If radar data is processed using traditional radar processing pipelines, then the processing is specialized for radar signals, but the system has higher costs and lower flexibility
Solution Approach 1:
The patent enables a single vision processing unit to handle both camera and radar data processing by converting radar data into camera interface frames. This universal approach allows the same hardware platform to be used for multiple sensing modalities, significantly reducing system cost and improving flexibility compared to having separate specialized processing systems.
Solution Approach 2:
The patent creates a virtual copy of camera interface frames from radar data by organizing radar signals into frames with camera interface format. This allows the radar processing system to leverage the existing camera processing pipeline and software ecosystem, avoiding the need to develop and manufacture separate specialized radar processing hardware.
3Productivity
If radar data is converted to camera interface frames, then multi-vector processors can process the data efficiently, but the radar data format must be adapted
Solution Approach 1:
The patent segments the radar data processing into distinct functional blocks: frame generation circuit that converts radar signals to camera interface frames, and frame processing circuit that processes the frames. This segmentation allows the complex format conversion to be handled by dedicated hardware circuits rather than software, improving processing efficiency while keeping the overall system architecture manageable.
Solution Approach 2:
The patent introduces camera interface frames as an intermediary data format between the radar signal processing stage and the vision processing stage. This intermediary format serves as a bridge that allows efficient data transfer and processing by multi-vector processors while maintaining compatibility with existing camera processing pipelines, thus improving productivity without excessive complexity.
4Device complexity
If a single multi-core vector processor is used for the entire signal chain, then device complexity is reduced, but the processing architecture must be simplified
Solution Approach 1:
The patent makes a single multi-core vector processor handle the entire signal chain from radar signal processing to frame generation and processing. This universal processor performs multiple functions that would traditionally require separate dedicated hardware blocks, reducing the number of devices while maintaining architectural flexibility through software-based processing pipelines.
