<?Pub Dtl?>This paper presents an energy-efficient feature extraction accelerator design aimed at visual navigation. The hardware-oriented algorithmic modifications such as a circular-shaped sampling region and unified description are proposed to minimize area and energy consumption while maintaining feature extraction quality. A matched-throughput accelerator employs fully-unrolled filters...
This paper investigates pipelining methodologies for the ultra low voltage regime. Based on an analytical model and simulations, we propose a pipelining technique that provides higher energy efficiency and performance than conventional approaches to ultra low voltage design. Two-phase latch based design and sequential circuit optimizations are also proposed to further improve energy efficiency and...
