Abstract

High power consumption has significantly increased the cooling cost in high-performance computation stations and limited the operation time in portable systems powered by batteries. Traditional power reduction mechanisms have limited traction in the post-Dennard Scaling landscape. Emerging research on new computation devices and associated architectures has shown three trends with the potential to greatly mitigate current power limitations. The first is to employ steep-slope transistors to enable fundamentally more efficient operation at reduced supply voltage in conventional Boolean logic, reducing dynamic power. The second is to employ brain-inspired computation paradigms, directly embodying computation mechanisms inspired by the brains, which have shown potential in extremely efficient, if approximate, processing with silicon-neuron networks. The third is 'let physics do the computation', which focuses on using the intrinsic operation mechanism of devices (such as coupled oscillators) to do the approximate computation, instead of building complex circuits to carry out the same function. This paper first describes these three trends, and then proposes the use of the hybrid-phase-transition-FET (Hyper-FET), a device that could be configured as a steep-slope transistor, a spiking neuron cell, or an oscillator, as the device of choice for carrying these three trends forward. We discuss how a single class of device can be configured for these multiple use cases, and provide in-depth examination and analysis for a case study of building coupled-oscillator systems using Hyper-FETs for image processing. Performance benchmarking highlights the potential of significantly higher energy efficiency than dedicated CMOS accelerators at the same technology node.
