The advent of digital computers has made the routine use of pattern-matching possible in various applications. This has also stimulated the development of many algorithms. In this paper, we propose a new algorithm that offers improved performance compared to those reported in the literature so far. The new algorithm has been evolved after analyzing the(More)
In this paper, we describe FLEXBUS, a flexible, high-performance onchip communication architecture featuring a dynamically configurable topology. FLEXBUS is designed to detect run-time variations in communication traffic characteristics, and efficiently adapt the <i>topology</i> of the communication architecture, both at the system-level, through <i>dynamic(More)
General-purpose System-on-Chip platforms consistingof configurable components are emerging as an attractivealternative to traditional, customized solutions (e.g., ASICs,custom SoCs), owing to their flexibility, time-to-market advantage,and low engineering costs. However, the adoptionof such platforms in many high-volume markets (e.g, wirelesshandhelds) is(More)
Major technologic and economic factors are driving a revolution in computer and communication system design. Networking applications like network processors, routers on chips and home gateways, portable products like wireless telephones and internet appliances, multimedia products like set-top boxes, and embedded controllers in automobiles, printers, and(More)
A graphics package has been developed to display the main chain torsion angles phi, psi (phi, Psi); (Ramachandran angles) in a protein of known structure. In addition, the package calculates the Ramachandran angles at the central residue in the stretch of three amino acids having specified the flanking residue types. The package displays the Ramachandran(More)
At-speed testing of GHz processors using external testers may not be technically and economically feasible. Hence, there is an emerging need for low-cost, high-quality self-test methodologies, which can be used by processors to test themselves at-speed. Currently, Built-In Self-Test (BIST) is the primary self-test methodology available and is widely used(More)
The occurrence of similar structural repeats in a protein structure has evolved through gene duplication. These repeats act as a structural building block and form more than one compact structural and functional unit called a repeat domain. The protein families comprising similar structural repeats are mainly involved in protein-protein interactions as well(More)
In this paper we introduce a novel concept that can be used for augmenting simulation based verification at the Register Transfer Level (RTL). In this technique the designer of an RTL circuit introduces some well understood extra behavior (through some extra circuitry) into the circuit under verification. This can be termed as design for verification.(More)
Conformation Angles DataBase (CADB) provides an online resource to access data on conformation angles (both main-chain and side-chain) of protein structures in two data sets corresponding to 25% and 90% sequence identity between any two proteins, available in the Protein Data Bank. In addition, the database contains the necessary crystallographic(More)
