Embedded Soft Processor for Sensor Networks

Abstract

The introduction of smarter and smaller application specific processors has opened doors to the world of intelligent sensor networks. This has led sensors to have their own onboard processing and communication units. These technological advancements have transcended sensors from performing trivial sensing functions to performing more complex operations like monitoring environmental changes, carry out surveillance etc. We are presenting a soft core design that can be easily modified and integrated with other processing units to implement different design features for sensor nodes. The soft core is implemented using Xilinx ISE design tools. The core has been implemented and tested successfully using cycle accurate timing simulation.
