Digital Content Addressable Memory and Time Domain Content Addressable Memory Usage in BCH Decoder

Abstract

This thesis presents a comprehensive exploration of the application of Content Addressable Memory (CAM) in the context of a BCH decoder. The research investigates both digital and time domain implementations to assess their performance and effectiveness. Three memory implementations, namely LUT-based memory, digital time domain memory, and Time Domain Content Addressable Memory (TDCAM), are thoroughly examined and compared. The evaluation is carried out using 65 nm CMOS technology, providing valuable practical insights into the capabilities and implications of these approaches.

The main objective of this study is to analyze the potential benefits and drawbacks of employing CAM in a BCH decoder, particularly in scenarios where multiple pattern searches are required. The focus is on optimizing the decoding process by leveraging the advantages of CAM technology. Furthermore, the thesis explores the usage of TDCAM in the time domain BCH decoder with an iterative process, highlighting its potential for enhancing decoding performance.

The comparative analysis sheds light on the advantages offered by CAM, with a particular emphasis on the TDCAM approach, in enhancing the soft BCH decoding process in the time domain. By leveraging the benefits of TDCAM, the thesis aims to contribute to the advancement of efficient and reliable data decoding techniques. The findings and observations presented in this research provide valuable insights for researchers and practitioners in the field, facilitating a better understanding of the potential applications and benefits of TDCAM in soft BCH decoding and offering a foundation for further advancements in this area.
