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 and ARM.This work proposes an uplink acceleration on an AMD graphics processor unit and OpenCL to show a new opportunity #N/A in 5th Generation New Radio HIGH-PHY.The key accelerators are the physical random access channel and the physical uplink shared channel Toys Other 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.
