Application of Timing Fault Detection to Rocket Core on FPGA
Ushio Jimbo, Ryota Shioya, Masahiro Goshima · 2018
Razor is the most famous technique for timing fault detection/recovery. In this paper, we apply Razor to a RISC-V core, Rocket. Rocket is kind of an out-of-order scalar processor, which causes problems with Razor. We clarify the problem and show how to solve it. We evaluated area overhead for the modification.
