Unix Kernel Architecture

Unix Kernel Architecture
The kernel runs the show, i.e. it manages all the operations in a Unix flavored
environment. The kernel architecture must support the primary Unix requirements. These
requirements fall in two categories namely, functions for process management and
functions for file management (files include device files). Process management entails
allocation of resources including CPU, memory, and offers services that processes may
need. The file management in itself involves ....etc

Hi, this is shaziya,i want some information about Genesis kernel:Spawning networks which is about creation of programmable child networks(dynamic) based on user requirements.
And also it can be formed using 3 components,
1)transport environment
2)programming environment
3)life cycle environment
Hope u understand my requirement.
Thank You ....etc

ABSTRACT


Today's Holler center is not something about phone calls. it's a separate business that must generate revenue. It must provide company with fresh ideas, must help company to get new customers and achieve business goals, it must work 24 hours a day, live response must be accessible within few seconds. Finally, the operator's response must solve customer problems immediately. The aim of this software ....etc

The limited built-in configurability of Linux can lead to expensive code size overhead when it is used in the embedded systems application. This problems can be overcome by the use of the link-time compaction that exploit the previously well known fixed runtime environment of many embedded systems. The ARM XScale and i386 platforms are used as the test platforms and with the proposed method, upto 16% reduction in the kernel memory footprint can be achieved. The proposed techniques can be implemented easily with simple additions to existing bin ....etc

Facial recognition using multisensor images based on localized kernel eigen spaces.

A feature selection technique along with an information fusion procedure for improving the recognition accuracy of a visual and thermal image-based facial recognition system is presented in this paper. A novel modular kernel eigenspaces approach is developed and implemented on the phase congruency feature maps extracted from the visual and thermal images individually. Smaller sub-regions from a predefined neighborhood within the phase congruency images of the ....etc

Unix System Kernel
Unix: Introduction
Operating System: a system that manages the resources
of a computer.
Resources: CPUs, Memory, I/O devices, Network
Kernel: the memory resident portion of Unix system
File system and process control system are two major
components of Unix Kernel.

Abstract
When kernel functionality is desired in userspace, thecommon approach is to reimplement it for userspace interfaces.We show that use of existing kernel file systemsin userspace programs is possible without modifyingthe kernel file system code base. Two different operatingmodes are explored: 1) a transparent mode, inwhich the file system is mounted in the typical fashionby using the kernel code as a userspace server, and 2) astandalone mode, in which applications can use a kernelfile system as a library. The first mode provides ....etc
