The Smart Chips for Smart Surroundings (4S) project finished in December 2007. Its aim was to create flexible and reconfigurable building blocks for new consumer devices and applications in for instance digital information broadcasting, ambient intelligence devices, and 3G/4G multimedia terminals.
The project provided proof of concept of power-efficient reconfigurable computing, and delivered 2 concept chips: a digital baseband chip and an analogue frontend chip. Recore contributed its Montium® IP and knowledge of reconfigurable SoCs to the project's digital baseband chip.
An ARM 9 General Purpose Processof and the project's digital baseband chip were compared for energy efficiency and speed. Including memory accesss, the Montium-based SoC reduced energy use when running non-power-of-two FFTs by a factor of 33 compared to the General Purpose Processor (excluding memory access). In a comparison of processing time, relative speed increased by a factor of 40.
4S was an EU Framework 6 project.
