This paper describes the architecture and performance of the JX operating system. JX is both an operating system completely written in Java and a runtime system for Java

The Android is an operating system for mobile devices such as cellular phones, table computersand netbooks. Android is developed by Google and is based upon the Linux Kernel and GNUsoftware. Android has a large community of developers writing application programs("apps") that extend the functionality of the devices. The Android operating SystemSoftware Stack consis...

Operating system (OS) emulation consists of running a binary executable intended for a particular OS on a different OS. This ability allows users to run more programs and OS manufacturers to jumpstart new OSs with non-native programs. There are several OSs that can run binaries compiled for the same processor but for different operating systems. There are also systems that can run multiple OS s...

The Cnonus technology has been designed for building o'new generations" of open, distributed, scalable Operating Systems. CHoRus has the following main characteristics: ¡ Ír comÍ[tnication-based technology, relying on a minimal Nucleus integrating distributed processing and communication at the lowest level, and providing generic services used by a set of subsystem servers to provide extended s...

Operating systems provide the fundamental mechanisms for securing computer processing. Since the 1960s, operating systems designers have explored how to build “secure” operating systems — operating systems whose mechanisms protect the system against a motivated adversary. Recently, the importance of ensuring such security has become a mainstream issue for all operating systems. In this book, we...

The course ‘Operating System Internals’ (OSI) usually focuses on teaching the concepts and issues surrounding the design of an OS in general. Students are advised to learn by example and through experiments, which are fundamental for the real understanding of operating system. Although controlled experiments with a commercial OS is one of basic approaches in organizing the practical work of stu...

Computers have brought about a revolution across all industries. Computers have become the most important part for the success of any enterprise. Computers are the best means for proper storage and management of data. They can assist as knowledge bases and can be utilized for financial transactions due to their processing power and storage capacities. PCs handle and keep a track of data which i...

A common way to workaround the drawbacks of higher-level communication toolkits is to program applications using lower-level mechanisms such as Sockets and System V TLI. These mechanisms are widely available under a variety of operating systems. Programming at this level provides the benefit of flexibility and performance, while shielding developers from the details of network and transport lay...

Embedded system has made great advance with the progress of semiconductor technology. System-on-chip (SOC) has provided more powerful functions for embedded systems. Scratchpad memory (SPM), which is softwarecontrolled on-chip memory, is used in embedded systems to reduce the speed gap between the processors and the memory and the power consumption of memory. The architecture of embedded softwa...

Pebble is a new operating system designed with the goals of flexibility, safety, and performance. Its architecture combines a set of features heretofore not found in a single system, including (a) a minimal privileged mode nucleus, responsible for switching between protection domains, (b) implementation of all system services by replaceable user-level components with minimal privileges (includi...
