Design of a secure, intelligent, and reconfigurable Web cam using a C based system design flow

摘要

This paper describes the design of a reconfigurable Internet camera, Cam-E-leon, combining reconfigurable hardware and embedded software. The software is based on the μClinux operating system. The network appliance implements a secure VPN (Virtual Private Network) with 3DES encryption and Internet camera server (including JPEG compression). The appliance's hardware can be reconfigured at run-time by the client, thus allowing to switch between several available image manipulation functions. This paper focuses on the design process used to implement the appliance starting from a high-level executable specification.
