Abstract:

Neuromorphic algorithms for computer-based vision may be the next step towards improving the way computers gather and interpret visual information. However, these algorithms typically have high computational demands making them difficult to deploy in embedded environments where power consumption is equally as important as performance. In this paper, we present an embedded implementation of a ventral visual pathway model, HMAX. We describe an embedded FPGA system that implements the model, as well as accelerator engines necessary to ensure adequate performance. The final system is shown to operate within a power budget of 3W while achieving up to 16.5X speedup over a pure embedded processor implementation.

I. Introduction

“Neuromorphic” algorithms are promising alternatives to classical computer vision approaches, where extracting objects of interest and classifying them are based on cortical models describing the brain. Unfortunately, biologically inspired algorithms tend to be limited to systems with high-power and large size due to their significant computational requirements.
