Abstract

Simultaneous localization and mapping (SLAM) is a quintessential problem in autonomous navigation, augmented reality, and virtual reality. In particular, low-power SLAM has gained increasing importance for its applications in power-limited edge devices such as unmanned aerial vehicles (UA Vs) and small- sized cars that constitute devices with edge intelligence. This article presents a 7.25-to-8.79-TOPS/W mixed-signal oscillator- based SLAM accelerator for applications in edge robotics. This stud
