A highly-integrated DSL modem for residential gateway applications is described. The chip integrates a C62x based DSL PHY, AFE, line driver and receiver, power management, and broadband controller subsystem. A 0.13/spl mu/m 5M CMOS process is used to implement the 2.3W chip. Supplies are 1.5V for digital and 3.3V for analog subsystems.
The evidence of UNDESA framework of sustainability assessment in MCDM paradigm is scarce generically and particularly, the status of sustainability of Indian states has never been assessed in accordance with UNDESA 2007 framework.

This paper is about encryption and decryption of images using a secret password provided by the user. The encryption machine takes the password and the source image as input and generates a key pattern image by using Secure Hash Algorithm (SHA) and a lock image by using Mcrypt algorithm. It provides additional security using Image scrambling. The decryption(More)
This paper is about encryption and decryption of text using a secret password provided by the user. The encryption machine takes the password and source message as input and generates acipher text based on Modified Playfair Algorithm using dynamic rectangular matrix. The decryption machine takes the same password and the cipher text generated by the(More)
