Becaus e most of the components of the transmitter and the receiver of such links are analog\, rather than digital\, they don't benefit as much from Moore' s law. On the other hand\, the need to transmit data ever faster calls for higher rates of transmission over existing electrical wires. Since in thi s type of communication noise is highly frequency dependent\, higher trans mission rates lead to much higher noise\, and therefore a much faster grow th of power consumption than linear. The industry has long recognized this problem as the "Interconnect bottleneck". Fundamental solutions to this i mportant issue have remained elusive\, however.\n\nA look at the capacity of these channels reveals that today we are only transmitting at anywhere between 1% to 4% of the capacity. Therefore\, at least on the surface\, th ere is a lot to be gained by applying methods from communication theory to this problem. However\, unlike many other systems such as wireless\, DSL\ , satellite\, or optical communication\, the constraints on the chip-to-ch ip communication system are very different: transmission rates are typical ly 1000 times higher than those encountered in wireless communication. On the other hand\, the energy allowed to be consumed for the transmission an d recovery of each bit is about 1000 times less than what is customary in wireless. Also\, latency requirements are extremely stringent\, allowing o nly latencies up to very few nanoseconds. Therefore\, it is not possible t o use fancy processing methods.\n\nIn this talk I will introduce a new mod ulation scheme for chip-to-chip communication which we call chord signalin g. This method is somewhat reminiscent of spatial MIMO systems\, and provi des a first step towards a better utilization of the available communicati on bandwidth between chips. Current implementations of systems based on th ese codes show a large reduction of total power of the communication PHY a nd a large increase of the communication speed compared to other classical systems.\n\nI will also talk about internship opportunities at the Advanc ed R&D Lab of Kandou in the areas of signal processing/modeling\, digital circuit design\, and analog circuit design. Interns will have the opportun ity to work on state-of-the art problems under the mentorship of internati onally recognized scientists and engineers.
