iniewski, I think what i understand from the article is: as more and more RF front end is used, using more adhoc control signals is simply not able to handle complex scenarios. A standardized bus interface will help ease the problem. It will take sometime before all radio can be integrated into just 1 chip.

After looking at the abstract of the SPMI specification at the MIPI website I'm little bit confused. SPMI is actually described as the system power management interface to control the power consumed by the micro processors. Anyways I think the development for the control interface of RF front end devices is only in the starting phase. With the current requirement on mobiles to support multiple RF standards the front end is really getting complex with many tunable components like filters, attenuators and power amplifiers. Things will be more clear when we have few different RF components where SPMI interface is already integrated.

Not sure I am understanding the concept. More and more RF circuitry gets integrated into one silicon chip (in some cases like Bluetooth even PA is integrated). When everything is one chip what is the point of standardization for control signals? Comments anyone?...Kris

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
