Design and Implementation of Fault Tolerant LZW for Reliable Data Compression Using Verilog HDL

Data Compression plays vital role in various domains, where efficient data storage and transmission are essential. Due to the vast amount of data that needs to be processed and transmitted in real-time, compression techniques are crucial in order to optimize the bandwidth and storage resources. The basic idea here is to develop a fault-tolerant implementation of the Lempel-Ziv-Welch algorithm using Verilog HDL. LZW is one such typical compression technique known for its effectiveness in reducing data size without significant data loss. However, many systems, for example Avionic systems demand higher levels of reliability and fault tolerance due to the critical nature of operations. Hence, to address this issue, the idea considered will incorporate fault tolerant mechanisms into LZW scheme. Effective replication of the LZW module can develop the fault tolerant system for the same which is a reliable, effective, and efficient data compression solution for an application. Integration of LZW with the fault-tolerant mechanisms ensures the system's resilience to failures and faults, thereby enhancing the safety of the system. This fault tolerance can thus be ensured by techniques such as Clock gating, Isolation Cells and Level Shifters which make sure of reliable data compression at the module level.
