There is a constant demand for increased data consumption around the world. The internet continues to expand with increased demand for video, social media, and business use. In addition, there are now almost 3 times as many Internet-Of-Things (IOT) devices connected than the world's population. In 2017, there were 20 billion internet connected devices and that number is expected to grow to 75 bil- lion by 2025. With this explosion in internet data usage, there is a constant need for more powerful data centres. Within data centres, there exists storage, servers, switches/hubs and networking gear. All of these components exist within large racks of equipment that require high speed SERDES over backplanes for interconnection and these SERDES need to keep increasing in speed to keep up with demand to move more data (SERDES are high speed communication channels between integrated circuits). While it is possible to keep increasing SERDES data rates, this comes at a cost of much higher power. However, the power dissipation for data centres is of great concern worldwide as it has been predicted that these data centres could consume 20 percent of global electricity by year 2025 and contribute up to 14 percent of global greenhouse emmisions by year 2040. Thus, reducing power in data centres is of critical concern. This project looks at new techniques to reduce power in these very high speed SERDES and therefore can help to reduce the power in future data centres.

世界各地不断需要增加数据消费。互联网继续 随着对视频、社交媒体和商业用途需求的增加而扩展。此外，现在还有 物联网（IOT）设备连接数量几乎是世界人口的3倍。在 2017年，有200亿台互联网连接设备，预计这一数字将增长到750亿。 狮子座2025年随着互联网数据使用的爆炸式增长，人们不断需要更强大的 数据中心。在数据中心内，有储存、服务器、交换机/集线器和网络设备。 所有这些组件都存在于需要高速SERDES的大型设备机架中。 这些SERDES需要不断提高速度以满足需求 移动更多的数据（SERDES是集成电路之间的高速通信通道）。虽然可以 保持增加SERDES数据速率，这是以更高的功率为代价的。 然而，在这方面， 数据中心的功率耗散在全世界都受到极大关注，因为据预测，到2025年，这些数据中心可能消耗全球电力的20%，到2040年，这些数据中心可能贡献全球温室气体排放的14%。 因此，降低数据中心的功率是一个关键问题。 该项目着眼于新技术，以减少 这些非常高速的SERDES中的功率，因此可以帮助降低未来数据中心的功率。
