Multiple Error Recovery in FIR Filter using Reduced-Precision Redundancy (RPR)

Cini George | Vrinda V. Gopal T

Abstract: In this paper, Reduced-Precision redundancy (RPR) technique is used to protect FIR Filter against single event upsets (SEUs). One of the radiation effect is Single Event Upset (SEU) which causes a logical bit changing in a device and results in an unrecoverable error in a system. RPR is a redundancy technique similar to TMR that requires less hardware overhead by using reduced-precision modules in two of its three replicas [1]. FIR Filters are common in the analog and digital communications. This paper introduces the RPR Technique to protect the FIR Filter and this is implemented in order to provide lower power consumption & reduced complexity. The performance of the proposed system is compared with SCTMR & SMERTMR in terms of hardware requirements. The proposed method is designed using VHDL on Xilinx ISE simulator
