FPGA-BASED IC SYSTEMS: UNRAVELING MYTHS FROM REALITY (POSTION PAPER)

摘要

This article presents a critical analysis of FPGAs compared to microprocessors with regards to their fundamental differences and, importantly, to their use in systems for nuclear power plants based on this technology. This analysis covers in particular the following issues: safety, performance, maintenance, cybersecurity, obsolescence, renovations, licensing and qualification. The resulting advantages and disadvantages of FPGAs compared to microprocessors are often presented in an over-simplified manner. This situation can create confusion regarding the distinction between properties that are inherent to the underlying technology and those that depend upon the specific product. This article provides explanations and analyses to inspire a deeper understanding of the aforementioned issues, and to help readers to better unravel myths from reality regarding FPGA-based I&C systems.
