Multiprocessor systems are becoming increasingly popular because of the increased throughput possible and the possibility of system availability despite the failure of some of the processing units. This paper describes an innovative concept in multiprocessor system design, and suggests some of the research areas which have not yet been resolved but which can be studied on this system. The syste...

This paper presents a scalable multiprocessor architecture with multiple access memories and multi-way busses. This parallel architecture with more intelligent memory model and efficient multi-way interconnection network organization is called as CRrCW (Concurrent Read and restricted Concurrent Write) scaleable multiprocessor system. The memory and network model provides concurrent memory acces...

Embedded systems – multiprocessor systems on a chip with application specific instruction-set processors (ASIPs) – become indivisible part of our everyday lives. They are everywhere. Therefore, powerful and flexible way of design and simulation of these systems is needed. The simulators of ASIPs are created using an architecture description language called ISAC. In this paper, the basic concept...

With the increasing availability of multiprocessor platforms based on dierent types of archi-tectures (shared memory, distributed memory, network based), users will be increasingly faced with heterogeneous and distributed multiprocessor computing facilities. Programming environment concepts have to be found which enable the user to program and use these heterogeneous computing resources, consis...

The state of modern computer systems has evolved to allow easy access to multiprocessor systems by supporting multiple processors on a single physical package. As the multiprocessor hardware evolves, new ways of programming it are also developed. Some inventions may merely be adopting and standardizing the older paradigms. One such evolving standard for programming shared-memory parallel comput...

Fault tolerance is often considered as a good additional feature for multiprocessor systems but nowadays it is becoming an essential attribute. Fault tolerance can be achieved by the use of dedicated customized hardware that may have the disadvantage of large cost. Another approach to fault tolerance is to exploit existing redundancy in multiprocessor systems via a task scheduling software stra...

Scheduling is the process which improves the performance of parallel and distributed systems. Multiprocessor is a powerful computing for real-time applications and their high performance is purely based on parallel and distributed systems. Number of scheduling tasks in homogeneous and heterogeneous multiprocessor systems is an important problem in computing because this problem is a NP-hard pro...

The problem of developing the architecture modern cognitive radar systems using artificial intelligence technologies is considered. main difference from traditional use a trained neural network. heterogeneous multiprocessor system rebuilt in process solving problem, providing reliability and various types problems one class deep learning network real time. This promotes introduction that take in...

Instruction–level multithreading is an architectural approach to tolerating long–latency memory accesses and synchronization delays in distributed–memory systems. The paper presents a timed Petri net model of a fine–grain multithreaded distributed–memory multiprocessor system at the instruction execution level, and illustrates performance analysis by results obtained from simulation of the deri...

In this paper we study global fixed-priority scheduling of periodic task systems upon identical multiprocessor platforms. Based on existing feasibility tests for periodic task systems upon identical multiprocessor platforms, we show (using a dummy priority assignment algorithm) that optimal priority assignment for these systems exists. Then we provide an algorithm based on RMUS[m/(3m−2)] that h...
