System Technology Co-Optimization for 6G computing hardware

PhD - Leuven | More than two weeks ago

Enable STCO methodology to enable disruptive computing techniques for 6G

The current vision of 6G requires the support of the THz band, novel antenna technologies, evolution of network topology, spectrum sharing, comprehensive AI, split computing, and high-precision network. Imec has a research program in System Technology Co Optimization (STCO) for key application spaces such as AR/VR, Distributed ML that have been identified as key enabler for 6G.


From a communication side, investigating frequencies above 100 GHz is necessary to provide sufficient bandwidth for wireless data rates up to 100 Gbit/s. However, one must manage the huge implementation complexity, power consumption and sensitivity to non-idealities of such systems. Together with higher throughput, new applications require guarantees on quality-of-service. This includes minimal latency for applications such as augmented reality, robustness in mobile scenarios, and simultaneous support for multiple users in office and outdoor scenarios. This will require to combine the high-throughput physical-layer pipeline with adaptive MAC protocols. From a technology innovation perspective, 6G system offers a big push for hybrid integration of communications plane, storage plane and computing planes consisting of technology devices optimized for each of these layers. 


This PhD will build on imec's experience of combining system-level constraints for technology or semiconductor innovation. The student will focus on the application and architecture level optimization to identify, explore and solve the bottlenecks of a 6G hardware. The system level PPAC (Power-Performance-Area-Cost) constraint evaluation for a 6G hardware would be the steppingstone to enable the innovation. The primary objective of this PhD would be to propose hybrid integration enablement using 3D technologies for computing systems for 6G. As a PhD student you will explore system architecture innovations needed to deliver the relevant performance for applications foreseen for the 6G network. The research will involve a fundamental breakthrough in system architecture definition while taking enabling device technology constraints in mind. This topic would be an example of the System-Technology-Co-Optimization (STCO) philosophy pursued in imec
