Hamming Codes

Hamming Code is yet another error detection and correction code. In this code, the parity bits are added to increase the Hamming distance between the valid code words. Here, the parity bits are arranged in a way that different error…

Error Detection and Correction Codes

Data errors in a digital system can happen due to faults in the transceiver system or noise during the transmission. Such errors need to be detected and corrected, as digital systems are sensitive to such errors. The presence of data…

Redundancy in Fault Tolerance

In the previous post we have understood the need of Fault Tolerance in VLSI System Design. A VLSI system can broadly be considered as a union of following 3 layers: Hardware Layer (Processing cores, Memories, etc.) Software Layer (OS, Program…

Circuit Design of Parity Generator

This post illustrates the circuit design of Even Parity Generator. State Machine diagram for the same Parity Generator has been shown below. Click here to realize how we reach to the following state transition diagram. Click here to learn the step…
