Synchronous to asynchronous conversion: A Case Study: The Blowfish algorithm Implementation

摘要

This work introduces a novel methodology that eases the synchronous to asymchronous conversion of existing digital circuits. Synchronous single-phased circuits may have its performance improved with the use of a variable rate clock generator if the conversion is done on some key circuits. This methodology is used to improve the performance of a soft-core implementation of the Blowfish cryptographic algorithm.
