Accelerated V2X Provisioning with Extensible Processor Platform
Accelerated V2X provisioning with Extensible Processor Platform Henrique S. Ogawa1, Thomas E. Luther1, Jefferson E. Ricardini1, Helmiton Cunha1, Marcos Simplicio Jr.2, Diego F. Aranha3, Ruud Derwig4 and Harsh Kupwade-Patil1 1 America R&D Center (ARC), LG Electronics US Inc. {henrique1.ogawa,thomas.luther,jefferson1.ricardini,helmiton1.cunha}@lge.com [email protected] 2 University of Sao Paulo, Brazil [email protected] 3 Aarhus University, Denmark [email protected] 4 Synopsys Inc., Netherlands [email protected] Abstract. With the burgeoning Vehicle-to-Everything (V2X) communication, security and privacy concerns are paramount. Such concerns are usually mitigated by combining cryptographic mechanisms with a suitable key management architecture. However, cryptographic operations may be quite resource-intensive, placing a considerable burden on the vehicle’s V2X computing unit. To assuage this issue, it is reasonable to use hardware acceleration for common cryptographic primitives, such as block ciphers, digital signature schemes, and key exchange protocols. In this scenario, custom extension instructions can be a plausible option, since they achieve fine-tuned hardware acceleration with a low to moderate logic overhead, while also reducing code size. In this article, we apply this method along with dual-data memory banks for the hardware acceleration of the PRESENT block cipher, as well as for the F2255−19 finite field arithmetic employed in cryptographic primitives based on Curve25519 (e.g., EdDSA and X25519). As a result, when compared with a state-of-the-art software-optimized implementation, the performance of PRESENT is improved by a factor of 17 to 34 and code size is reduced by 70%, with only a 4.37% increase in FPGA logic overhead. -

High-Speed Soft-Processor Architecture for FPGA Overlays
High-Speed Soft-Processor Architecture for FPGA Overlays by Charles Eric LaForest A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Graduate Department of Electrical and Computer Engineering University of Toronto c Copyright 2015 by Charles Eric LaForest Abstract High-Speed Soft-Processor Architecture for FPGA Overlays Charles Eric LaForest Doctor of Philosophy Graduate Department of Electrical and Computer Engineering University of Toronto 2015 Field-Programmable Gate Arrays (FPGAs) provide an easier path than Application- Specific Integrated Circuits (ASICs) for implementing computing systems, and generally yield higher performance and lower power than optimized software running on high- end CPUs. However, designing hardware with FPGAs remains a difficult and time- consuming process, requiring specialized skills and hours-long CAD processing times. An easier design process abstracts away the FPGA via an \overlay architecture", which implements a computing platform upon which we construct the desired system. Soft- processors represent the base case of overlays, allowing easy software-driven design, but at a large cost in performance and area. This thesis addresses the performance limitations of FPGA soft-processors, as building blocks for overlay architectures. We first aim to maximize the usage of FPGA structures by designing Octavo, a strict round-robin multi-threaded soft-processor architecture tailored to the underlying FPGA and capable of operating at maximal speed. We then scale Octavo to SIMD and MIMD parallelism by replicating its datapath and connecting Octavo cores in a point-to-point mesh. This scaling creates multi-local logic, which we preserve via logical partitioning to avoid artificial critial paths introduced by unnecessary CAD optimizations. -
