Towards a very high bandwidth wireless battery powered device

We discuss the hardware and software challenges in building a 2 Mbit per second wireless battery powered communications device. Of primary importance is power dissipation. To achieve aggressive power targets, a host of new techniques are required at all levels of the design hierarchy. Techniques for parallelizing saturating arithmetic will become important because of the software optimizations they enable. Highly configurable programmable structures will enable multiprotocol SOC solutions. To program complex SOCs, new compiler techniques will be required. Hardware implementations will need to be intimately aware of these software techniques. In particular both signal processing code written in C and control code written in Java will drive new compilation techniques to enable broadband 3G wireless systems
