Abstract
FPGA emerges as a very promising AI chip and algorithm hardware accelerator. However, the FPGA is susceptible to complex and changeable environment, which leads to circuit configuration information faults. To address this issue, we propose FTEI, a fault tolerance model of FPGA with endogenous immunity. At fault detection phase, we put forward a fault detection models based on optimized logistic regression classification and use it to establish a fault model matching library. During fault recover stage, we use fault configuration library and online evolution to recover faults. In order to improve the success ratio of online evolution, we propose RLAGA, an adaptive genetic algorithm based on reinforcement learning. Experiments on typical functional circuits, 8-bit parity verifier and 2-bit multiplier, demonstrate that the fault detection accuracy rates reach 94.4% and 93.2%, and the fault recover success rates of RLAGA are 100% and 90%, which significantly improves FPGA errors detection and recover effectiveness.
