AMD GPU-Based Selected Acceleration of PRACH and PUSCH in 5G NR

Blog Article

The software-defined physical layer is a recent trend in the 5G/B5G open radio access network.Most implementations are based on a central processing unit, i.e., Intel XEON kiara sky allure and ARM.

This work proposes an uplink acceleration on an AMD graphics processor unit and OpenCL to show a new opportunity in 5th Generation New Radio HIGH-PHY.The key accelerators are the physical random access air force ocp officer ranks channel and the physical uplink shared channel under a real-time test environment.Referring to 5G NR, we balance and match slot formats and GPU resources to ensure the PHY works properly on the AMD MI.50 with fine-tuned parallelism and memory mapping.

This work suggests that the AMD GPU is suitable for 5G ORAN.
