Demo abstract: netamorph: field-programmable analog arrays for energy-efficient sensor networks

Published: 08 April 2013 Publication History

Abstract

The limited power budgets of sensor networks necessitate some level of in-network pre-processing to reduce communication overhead. The low power consumption of analog signal processing (ASP) is well-suited for this task. However, the quick adoption of this technology has been restrained by the fact that ASP implementation requires a priori knowledge of the application space. Our solution to this challenge is to enable run-time reconfiguration through the use of a field-programmable analog array (FPAA). In the same way that reconfigurable digital systems allow system designers to change the infrastructure of digital blocks, an FPAA allows an application developer to change the infrastructure of, and even tune, ASP blocks without circuit-level expertise. We will demonstrate that an FPAA can be used to (1) facilitate the use of ASP to reduce power consumption, and to (2) allow run-time reconfigurability to maximize ASP impact.
