Chu, Chi-Chun (Ambrose)2008-07-162008-07-1620082008-07-16http://hdl.handle.net/1828/1026We first propose a reconfigurable processor, which consists of a MicroBlaze processor augmented with a Field-Programmable Gate Array (FPGA) to mitigate the computing time for public-key cryptography algorithms. We first consider Virtex-II Pro from Xilinx to analyze the potential solution of a Field-Programmable Custom Computing Machine (FCCM), which is composed of MicroBlaze augmented with a Virtex-II FPGA. We then propose a cryptography-oriented reconfigurable array, called CryptoRA, that efficiently supports long-word integer addition, subtraction and comparison. As a result, RISC processor can potentially be augmented with the CryptoRA rather than Virtex-II. The three main features that CryptoRA has are: (i) an increased granularity of the logic tile, (ii) the extension of the dedicated carry chain over the horizontal direction, and (iii) the incremental splitting Look-Up Table. According to our simulations, the CryptoRA-based FCCM provides a significant performance improvement over an optimized pure-software solution at an acceptable cost.enAvailable to the World Wide WebFPGACryptographyReconfigurableEmbedded systemUVic Subject Index::Sciences and Engineering::Applied SciencesThesisAmbrose Chu, Scott Miller, and Mihai Sima, ”Reconfigurable Solutions for Very-Long Arithmetic with Application in Cryptography.” The 18th edition of ACM Great Lakes Symposium on VLSI (GLSVLSI’08), Orlando, Florida, USA.
