Software Aspects of the Digital RF Processor (DRPTM)

This paper presents an overview of software aspects of the first-ever single-chip GSM radio realized in 90 nm CMOS. It demonstrates benefits of using highly programmable digital control logic in a wireless SoC system. It also describes a micro-processor design in the digital RF processor (DRP) and how it controls compensation for process, voltage, temperature (PVT) variations of the analog and RF circuits to meet the required RF performance.
