Software-Defined Radio Demodulation With CPU-FPGA-GPU Processing

The patent combines CPU, FPGA, and GPU into a hybrid processing system. The CPU handles general computations and control, the FPGA provides parallel processing for signal processing tasks, and the GPU handles computationally intensive algorithms. This merging of different processing architectures enables the system to achieve both ease of manufacture and sufficient computing power for complex modulation and algorithms.

The patent segments the processing tasks among different components: the FPGA handles streaming and serial processing for real-time digital communication requirements, while the GPU handles computationally intensive algorithms. This segmentation allows each component to specialize in its strengths, with the FPGA providing deterministic real-time performance and the GPU providing high computational power for complex operations.

The patent implements a universal processing system where the CPU, FPGA, and GPU can handle multiple types of processing tasks. The system can dynamically allocate tasks to different components based on their capabilities, making the complex hardware architecture function as a unified, multi-functional processing platform that can adapt to different communication protocols and processing requirements.

The patent implements dynamic reprogramming capabilities in the FPGA and GPU components, allowing the system to adapt to different wireless protocols and communication standards. The programmable nature of these components enables the system to change its processing architecture and algorithms on-the-fly, providing high adaptability while managing complexity through software configuration rather than hardware redesign.
