CPRI is a standard for communication between a Radio Equipment Controller (REC) or Base Station and one or more Radio Equipment (RE) units in a cellular network. By defining a publicly available specification for the key internal interface between these units, an independent technology evolution is fostered for cellular equipment products. The following figure shows the position of the interface within a cellular system. The CPRI v8.12 core has been designed to the CPRI Specification v7.0.

The CPRI core implements Layer 1 and Layer 2 of the CPRI specification in AMD Versal™ adaptive SoC, AMD UltraScale™ devices, AMD Zynq™ 7000 SoCs, and 7 series devices.
