On the design of a self-reconfigurable SoPC based cryptographic engine

Abstract

This paper presents a SoPC (System-on-a-Programmable-Chip) embedded system featuring self-reconfigurable capability. It addresses the factors that limit the system performance when FPGAs are used to implement various encryption algorithms dynamically. The limiting factors are the data transfer rate between the host and the FPGA, and the reconfiguration latency. The results generated by the cryptographic engine reported in this paper show that in order to attain optimal performance, it is crucial to floor-plan the reconfigurable part of the FPGA.
