O-RAN Central Unit and Distributed Unit
●O-RAN standards define the central unit as the entity responsible for Transport/S1, PDCP andRRC/Control plane processing in an option 2 split configuration. Deployment options range widely from low-end in-building processing with ≤25-50Gbps capacity to scale-out scenarios supporting multiple Tbps aggregate processing.
●The distributed unit is responsible for MAC/RLC and High-PHY processing, implemented as C code on general-purpose (eg Arm) devices. Cost and power are minimized by using optimized(Arm NEON) SIMD kernels and a look-aside accelerator device for forward error correction andDSP processing acceleration.
