Automatic Generation of Heterogeneous SoC Architectures With Secure Communications

Abstract

Heterogeneous multiprocessor system-on-chip (MPSoC) architectures allow designers to achieve energy efficiency and high performance, especially when tailored for the target applications. This specialization requires to select the MPSoC components and define their interconnections (on the architecture side), and also to determine the mapping and scheduling of tasks and communications (on the application side). This problem is exacerbated by the growing privacy and security concerns when these architectures elaborate sensitive data. We propose a co-design solution based on ant colony optimization that also protects the exchange of private data among components. Our solution generates architectures with secure communications with systematically better performance than architectures with predefined security solutions.
