The role of the operator for the Intel® vRAN Dedicated Accelerator ACC100 card is to orchestrate and manage the resources/devices exposed by the card within the OpenShift cluster. The operator is a state machine which will configure the resources and then monitor them and act autonomously based on the user interaction.
The operator design for Intel® vRAN Dedicated Accelerator ACC100 consist of:

# Intel® ACC200 vRAN Dedicated Accelerator

The Intel® vRAN Dedicated Accelerator ACC200 peripheral enables cost-effective 4G and 5G next-generation virtualized Radio Access Network (vRAN) solutions integrated on Sapphire Rapids Edge Enhanced Processor (SPR-EE) Intel® 7 based Xeon® multi-core server processor.

The ACC200 includes a 5G Low Density Parity Check (LDPC) encoder/decoder, rate match/dematch, Hybrid Automatic Repeat Request (HARQ) with access to DDR memory for buffer management, a 4G Turbo encoder/decoder, a Fast Fourier Transform (FFT) block providing DFT/iDFT processing offload for the 5G Sounding Reference Signal (SRS), a Queue Manager (QMGR), and a DMA subsystem. There is no dedicated on-card memory for HARQ, this is using coherent memory on the CPU side.
