  7. Abstract:
  8. In the upward trend of advancing technologies in chips manufacturing, utilizing Network on Chip (NOC) solutions is a sensible approach towards overcoming challenges in System on Chip (SOC). The most common form of NOC is the Wired NOC. The continuous physical size reduction of electronic circuits has led to bandwidth deficiency as well as increased temperature in various parts of these circuits. The vast advancement in chips manufacturing industry has made it possible to embed and adapt telecommunication equipment into chips, giving rise to Wireless NOC (WNOC) manufacturing. However, wireless communication increases fault rate; thereby, the system becomes more vulnerable against transient and trivial errors. One way to improve the reliability is the use of encoding techniques in large-scaled wireless networks. This thesis investigates the implication of vigorous error detection and correction algorithm, Reed-Solomon, which is most effectively used in large-scaled telecommunication systems, and thereafter, a suitable encoder and a decoder are designed and implemented to be used in NOC. The aim is to lower the energy consumption by using pipeline to shorten the time spent in encoding and decoding phase of the Reed-Solomon algorithm. Further, this thesis compares and illustrates differences of the result with the popular approach of Hamming codes. Even though this method features higher power consumption, it can be implemented on chip. Finally, the simulations performed in this study highlight the considerable gain in error detection and correction of the solution compared to the Hamming codes
