In the RAN environment, DU does the most of heavy lifting, running in real-time, and is the most compute intensive. DU must deliver an optimal performance on par with conventional BBU.
The CPU on the DU perform process the baseband signal. To make the processing more efficient, a HW acceleration card could be used to offload the selected functions of baseband processing.
We focused on system and CPU power consumed by DU platform (15G and 16G) while delivering a specifically designed load on the network.
