ISSN (Online) 2278-1021 IJARCCE ISSN (Print) 2319 5940 International Journal of Advanced Research in Computer and Communication Engineering Vol. 4, Issue 11, November 2015 Comparison of Contemporary Real Time Operating Systems Mr. Sagar Jape1, Mr. Mihir Kulkarni2, Prof.Dipti Pawade3 Student, Bachelors of Engineering, Department of Information Technology, K J Somaiya College of Engineering, Mumbai1,2 Assistant Professor, Department of Information Technology, K J Somaiya College of Engineering, Mumbai3 Abstract: With the advancement in embedded area, importance of real time operating system (RTOS) has been increased to greater extent. Now days for every embedded application low latency, efficient memory utilization and effective scheduling techniques are the basic requirements. Thus in this paper we have attempted to compare some of the real time operating systems. The systems (viz. VxWorks, QNX, Ecos, RTLinux, Windows CE and FreeRTOS) have been selected according to the highest user base criterion. We enlist the peculiar features of the systems with respect to the parameters like scheduling policies, licensing, memory management techniques, etc. and further, compare the selected systems over these parameters. Our effort to formulate the often confused, complex and contradictory pieces of information on contemporary RTOSs into simple, analytical organized structure will provide decisive insights to the reader on the selection process of an RTOS as per his requirements. Keywords:RTOS, VxWorks, QNX, eCOS, RTLinux,Windows CE, FreeRTOS I. INTRODUCTION An operating system (OS) is a set of software that handles designed known as Real Time Operating System (RTOS). computer hardware. Basically it acts as an interface The motive behind RTOS development is to process data between user program and computer hardware. -

It describes computers with multiple processing elements that perform the same operation on multiple data simultaneously. Thus, such machines exploit data level parallelism. History The first use of SIMD instructions was in vector supercomputers of the early 1970s such as the CDC Star-100 and the Texas Instruments ASC, which could operate on a vector of data with a single instruction. Vector processing was especially popularized by Cray in the 1970s and 1980s. Vector-processing architectures are now considered separate from SIMD machines, based on the fact that vector machines processed the vectors one word at a time through pipelined processors (though still based on a single instruction), whereas modern SIMD machines process all elements of the vector simultaneously.[1] The first era of modern SIMD machines was characterized by massively parallel processing-style supercomputers such as the Thinking Machines CM-1 and CM-2. These machines had many limited-functionality processors that would work in parallel. -
Generic Pipelined Processor Modeling and High Performance
Generic Pipelined Processor Modeling and High Performance Cycle-Accurate Simulator Generation Mehrdad Reshadi, Nikil Dutt Center for Embedded Computer Systems (CECS), Donald Bren School of Information and Computer Science, University of California Irvine, CA 92697, USA. {reshadi, dutt}@cecs.uci.edu simulators were more limited or slower than their manually generated Abstract counterparts. Detailed modeling of processors and high performance cycle- Colored Petri Net (CPN) [1] is a very powerful and flexible accurate simulators are essential for today’s hardware and software modeling technique and has been successfully used for describing design. These problems are challenging enough by themselves and parallelism, resource sharing and synchronization. It can naturally have seen many previous research efforts. Addressing both capture most of the behavioral elements of instruction flow in a simultaneously is even more challenging, with many existing processor. However, CPN models of realistic processors are very approaches focusing on one over another. In this paper, we propose complex mostly due to incompatibility of a token-based mechanism for the Reduced Colored Petri Net (RCPN) model that has two capturing data hazards. Such complexity reduces the productivity and advantages: first, it offers a very simple and intuitive way of modeling results in very slow simulators. In this paper, we present Reduced pipelined processors; second, it can generate high performance cycle- Colored Petri Net (RCPN), a generic modeling approach for accurate simulators. RCPN benefits from all the useful features of generating fast cycle-accurate simulators for pipelined processors. Colored Petri Nets without suffering from their exponential growth in RCPN is based on CPN and reduces the modeling complexity by complexity. -

A given ISA may be implemented with different microarchitectures.[1] Implementations might vary due to different goals of a given design or due to shifts in technology.[2] Computer architecture is the combination of microarchitecture and instruction set design. Relation to instruction set architecture The ISA is roughly the same as the programming model of a processor as seen by an assembly language programmer or compiler writer. The ISA includes the execution model, processor registers, address and data formats among other things. The Intel Core microarchitecture microarchitecture includes the constituent parts of the processor and how these interconnect and interoperate to implement the ISA. The microarchitecture of a machine is usually represented as (more or less detailed) diagrams that describe the interconnections of the various microarchitectural elements of the machine, which may be everything from single gates and registers, to complete arithmetic logic units (ALU)s and even larger elements.
