چکیده

This paper presents Fault Tolerant Carry Select Adder (FT-CSA), most widely used type of adder, based on the self checking scheme with modular architecture. The error recovery capability is derived using generic input/output combination of carry select adder with predetermined fault and error set. The experimental results show that proposed FT-CSA has nearly 50% overhead compared with the typical CSA without fault-tolerant scheme but achieves the significant improvement compared with typical redundancy scheme.

Carry checking/parity prediction adders and ALUs

In this paper, we present efficient self-checking implementations valid for all existing adder and arithmatic and logic unit (ALU) schemes (e.g., ripple carry, carry lookahead, skip carry schemes). Among all the known self-checking adder and ALU designs, the parity prediction scheme has the advantage that it requires the minimum hardware overhead for the adder/ALU and the minimum hardware overh...

Design and Characterization of Fault Tolerant Power Parallel Prefix Adders using FPGA Design

Parallel-prefix adders (also known as carry tree adders) are known to have the best performance in VLSI designs. However, this performance advantage does not translate directly into FPGA implementations due to constraints on logic block configurations and routing overhead. This paper investigates three types of carry-tree adders (the Kogge-Stone, sparse Kogge-Stone, and spanning tree adder) and...

Fault-tolerant, Real-time Reconfigurable Prefix Adder

In this paper, we assimilate and integrate two recent developments in prefix adder design and theory to create a fault-tolerant, real-time reconfigurable prefix adder. By exploiting the inherent redundancy of a Kogge-Stone adder we are able to extract signals to detect and correct from a single-fault. Our 16-bit design consumes less than 44% the hardware overhead of a comparable triple modular ...
