Communication Centric Microelectronic Design

We wish to undertake research into communication centricmicroelectronic design methods which are in contrast to today'scomputation centric (or gate-level) techniques. We believe thatthis research is timely since electronics is at the cusp of change.For the last 60 years, digital gates have been costly to produce andhave limited performance. We are now entering an era where the wires,which were once almost free, becoming the cost and performancelimiter. This trend is well documented in the InternationalTechnology Roadmap for Semiconductors (ITRS) roadmap which clearlyidentifies the step change needed in circuits and associated designtechniques. They also identify spiralling design complexity,escalating power densities and associated thermal problems.We believe that networks-on-chip resolve many of the design challengesfor future nano CMOS implementation technologies. Our backgroundresearch in this area has already resulted in a low latencynetwork-on-chip architecture which we have fabricated on 180nm CMOS.This initial work focused on interconnect between a tiled processorarchitecture which we have been developing with MIT. However, forthis project we wish to go much further, looking at communication atmany levels and for a range of technologies, from ASIC design on CMOSchips through to new field programmable gate array (FPGA)architectures. FPGA architecture is a departure from our usual lineof research, so we have been particularly grantified to receivea fully funded PhD studentship from Altera UK (one of the two biginternational FPGA companies) who will collaborate with us on thisproject.
