Multi Microprocessors

Ada for Multi-Microprocessors

Multi-processor systems are becoming more prevalent due to the many advantages which they offer over single-processor systems. A multi-microprocessor system can smoothly accommodate expansion and increasing levels of integration of separate controllers, facilitating modernization of industrial plants without large capital outlay. This book deals with the ways in which Ada can be used for such distributed systems. The main part of the book is devoted to the issue of how to construct and run an Ada program for a variable target configuration of several microcomputers, interconnected through shared memories, multi-access busses, local area networks or end-to-end lines. It is recognized that Ada and current Ada Programming Support Environments (APSEs) do not address distributed targets, and different approaches are therefore considered for coping with distribution without changing the language or unduly restricting the way in which it is used. The approach which emerges as the most natural is one where the designer is required to cluster tightly coupled Ada tasks into 'virtual nodes'. The implications of this approach for the user and the APSE are examined in detail, and further implications concerning use of the multi-microprocessor approach to achieve reliability and extensibility are also studied.

Multicore Processors and Systems

Multicore Processors and Systems provides a comprehensive overview of emerging multicore processors and systems. It covers technology trends affecting multicores, multicore architecture innovations, multicore software innovations, and case studies of state-of-the-art commercial multicore systems. A cross-cutting theme of the book is the challenges associated with scaling up multicore systems to hundreds of cores. The book provides an overview of significant developments in the architectures for multicore processors and systems. It includes chapters on fundamental requirements for multicore systems, including processing, memory systems, and interconnect. It also includes several case studies on commercial multicore systems that have recently been developed and deployed across multiple application domains. The architecture chapters focus on innovative multicore execution models as well as infrastructure for multicores, including memory systems and on-chip interconnections. The case studies examine multicore implementations across different application domains, including general purpose, server, media/broadband, network processing, and signal processing. Multicore Processors and Systems is the first book that focuses solely on multicore processors and systems, and in particular on the unique technology implications, architectures, and implementations. The book has contributing authors that are from both the academic and industrial communities.
