On-line self-recovery of embedded multi-processor SOC on FPGA using dynamic partial reconfiguration.
Information technology and control, Vol. 41, No. 2, 2012, pp. 116-214.
An error-recovery method for embedded multi-processor systems on SRAM-based FPGAs is proposed.
This method is effective against soft-errors in the configuration memory, such as the errors caused
by hIgh energy radiation also known as Single Event Upsets. The error-recovery algorithm performs on-line
test of the ~PGA configuration memory and recovers errors using dynamic partial reconfiguration.
Processor cores perform a dIstributed recovery procedure. If a failure occurs in the processor currently
runOing the recovery algOrithm, another processor core takes the role and performs reconfiguration.
Presented case study demonstrates the advantage of the proposed approach.
