Automating the Multiprocessing Environment

Automating real-time multi-threaded application development

Over the past decade, the advances made in VLSI devices have driven the development of cost-effective, symmetric multiprocessor architectures. In turn, operating systems have evolved to take advantage of the true concurrency offered by these architectures. However, because of the lack of adequate development tools, delivery of the intrinsic benefits of these platforms directly to applications h...

Benchmarking Multiprocessing Parameters in a Virtualized Multi-Core Environment

A virtualized multi-core environment is a multi-core machine running virtual machines with multiple virtual cpus. Previous research has demonstrated that the performance of multi-threaded, disk intensive, and network intensive applications in such an environment can be greatly improved by correctly tuning certain simple multiprocessing related system parameters like cpu affinity and interrupt a...

Practical System Design and Debug Considerations for Multiprocessing in the Embedded Environment

EME - low-cost embedded multiprocessing environment

This paper presents EME, a low-cost solution for a highly modular multiprocessing hardware-software environment useful in designing autonomous mobile robots. High processing capabilities, the ability to interface a large number of sensors and actuators, extensibility, redundancy and exibility are issues addressed by this environment. An autonomous robot equipped with two cameras, one for line-f...

Evaluation of a Dual-Core SMP and AMP Architecture based on an Embedded Case Study

Typical telecom applications apply a planar architecture pattern based on the processing requirements of each subsystem. In a symmetric multiprocessing environment all applications share the same hardware resources. However, currently embedded hardware platforms are being designed with asymmetric multiprocessor architectures to improve separation and increase performance of noninterfering tasks...
