This new volume introduces various VLSI (very-large-scale integration) architecture for DSP filters, speech filters, and image filters, detailing their key applications and discussing different aspects and technologies used in VLSI design, models and architectures, and more. The volume explores the major challenges with the aim to develop real-time hardware architecture designs that are compact and accurate. It provides useful research in the field of computer arithmetic and can be applied for various arithmetic circuits, for their digital implementation schemes, and for performance considerations.

Secure communication is the prime requirement of every organization. In today¿s world the security has become the major aspect of life. One essential aspect for secure communications is that of secret key Cryptography. It includes the process of encryption that converts plain-text into cipher-text. The process of decryption reconverts the cipher-text into plain-text. Various models were developed for the encryption in which keys were generated from the available data. Data Encryption Standard (DES) is the most commonly used algorithm for security purpose that was announced by National Bureau of Standard. It is the strongest algorithm but due to large processing time, it can be easily broken by the eavesdroppers.
