Real World Multicore Embedded Systems by Kenn Luecke Pdf

Efficient software development requires adequate toolsets to assist the developer in analyzing and optimizing a software application’s performance. With the relatively recent advent of multicore embedded hardware platforms, toolsets for supporting multicore development have appeared, although, in some cases, capabilities may be missing or immature, leaving software developers to manually massage outputs from one tool into inputs for the next tool or struggling to investigate unexpected multicore behaviors. This section reviews those multicore tools currently available for software developers as well as those that are still needed for adequate support.

Multicore Systems On-Chip: Practical Software/Hardware Design by Abderazek Ben Abdallah Pdf

System on chips designs have evolved from fairly simple unicore, single memory designs to complex heterogeneous multicore SoC architectures consisting of a large number of IP blocks on the same silicon. To meet high computational demands posed by latest consumer electronic devices, most current systems are based on such paradigm, which represents a real revolution in many aspects in computing. The attraction of multicore processing for power reduction is compelling. By splitting a set of tasks among multiple processor cores, the operating frequency necessary for each core can be reduced, allowing to reduce the voltage on each core. Because dynamic power is proportional to the frequency and to the square of the voltage, we get a big gain, even though we may have more cores running. As more and more cores are integrated into these designs to share the ever increasing processing load, the main challenges lie in efficient memory hierarchy, scalable system interconnect, new programming paradigms, and efficient integration methodology for connecting such heterogeneous cores into a single system capable of leveraging their individual flexibility. Current design methods tend toward mixed HW/SW co-designs targeting multicore systems on-chip for specific applications. To decide on the lowest cost mix of cores, designers must iteratively map the device’s functionality to a particular HW/SW partition and target architectures. In addition, to connect the heterogeneous cores, the architecture requires high performance complex communication architectures and efficient communication protocols, such as hierarchical bus, point-to-point connection, or Network-on-Chip. Software development also becomes far more complex due to the difficulties in breaking a single processing task into multiple parts that can be processed separately and then reassembled later. This reflects the fact that certain processor jobs cannot be easily parallelized to run concurrently on multiple processing cores and that load balancing between processing cores – especially heterogeneous cores – is very difficult.

Multi-Core Embedded Systems by Georgios Kornaros Pdf

Details a real-world product that applies a cutting-edge multi-core architecture Increasingly demanding modern applications—such as those used in telecommunications networking and real-time processing of audio, video, and multimedia streams—require multiple processors to achieve computational performance at the rate of a few giga-operations per second. This necessity for speed and manageable power consumption makes it likely that the next generation of embedded processing systems will include hundreds of cores, while being increasingly programmable, blending processors and configurable hardware in a power-efficient manner. Multi-Core Embedded Systems presents a variety of perspectives that elucidate the technical challenges associated with such increased integration of homogeneous (processors) and heterogeneous multiple cores. It offers an analysis that industry engineers and professionals will need to understand the physical details of both software and hardware in embedded architectures, as well as their limitations and potential for future growth. Discusses the available programming models spread across different abstraction levels The book begins with an overview of the evolution of multiprocessor architectures for embedded applications and discusses techniques for autonomous power management of system-level parameters. It addresses the use of existing open-source (and free) tools originating from several application domains—such as traffic modeling, graph theory, parallel computing and network simulation. In addition, the authors cover other important topics associated with multi-core embedded systems, such as: Architectures and interconnects Embedded design methodologies Mapping of applications

Smart Multicore Embedded Systems by Massimo Torquati,Koen Bertels,Sven Karlsson,François Pacull Pdf

This book provides a single-source reference to the state-of-the-art of high-level programming models and compilation tool-chains for embedded system platforms. The authors address challenges faced by programmers developing software to implement parallel applications in embedded systems, where very often they are forced to rewrite sequential programs into parallel software, taking into account all the low level features and peculiarities of the underlying platforms. Readers will benefit from these authors’ approach, which takes into account both the application requirements and the platform specificities of various embedded systems from different industries. Parallel programming tool-chains are described that take as input parameters both the application and the platform model, then determine relevant transformations and mapping decisions on the concrete platform, minimizing user intervention and hiding the difficulties related to the correct and efficient use of memory hierarchy and low level code generation.

Software Engineering for Embedded Systems by Srinivasa Addepalli Pdf

Embedded networking applications are changing and evolving quickly. Embedded multicore technology, for example, is appearing not only in high-end networking applications, but even in mid- and low-end networking applications. Achieving networking performance is only possible if software takes advantage of multiple cores. Multicore programming is not as simple as single-core programming. A new mindset is required, from architecting, designing to coding. Networking application development in multicore SoCs should not only concentrate on achieving scalable performance, but should also ease development and result in software that is maintainable for a long time. Some of the programming techniques listed in this chapter should help in achieving this goal.

This chapter will introduce the concepts of multicore related issues, while the subsequent chapters will go into further details. We will start with a general analysis of how electronic design trends lead to multicore hardware-software architectures as the only viable solution addressing consumer requirements on cost, performance and power. We will then categorize multicore architecture concepts by processing and communication requirements and show how different processing techniques combine to form multicore architectures that address the specific needs of different application domains. Special attention will be given to the programmability of the different hardware architectures and the impact that hardware has on software. We will close the chapter with a brief review of existing hardware architectures available on the market, as well as a brief discussion about programming models capable of expressing parallel functionality, which can then be mapped into multiple processor cores.

Advanced Multicore Systems-On-Chip by Abderazek Ben Abdallah Pdf

From basic architecture, interconnection, and parallelization to power optimization, this book provides a comprehensive description of emerging multicore systems-on-chip (MCSoCs) hardware and software design. Highlighting both fundamentals and advanced software and hardware design, it can serve as a primary textbook for advanced courses in MCSoCs design and embedded systems. The first three chapters introduce MCSoCs architectures, present design challenges and conventional design methods, and describe in detail the main building blocks of MCSoCs. Chapters 4, 5, and 6 discuss fundamental and advanced on-chip interconnection network technologies for multi and many core SoCs, enabling readers to understand the microarchitectures for on-chip routers and network interfaces that are essential in the context of latency, area, and power constraints. With the rise of multicore and many-core systems, concurrency is becoming a major issue in the daily life of a programmer. Thus, compiler and software development tools are critical in helping programmers create high-performance software. Programmers should make sure that their parallelized program codes will not cause race condition, memory-access deadlocks, or other faults that may crash their entire systems. As such, Chapter 7 describes a novel parallelizing compiler design for high-performance computing. Chapter 8 provides a detailed investigation of power reduction techniques for MCSoCs at component and network levels. It discusses energy conservation in general hardware design, and also in embedded multicore system components, such as CPUs, disks, displays and memories. Lastly, Chapter 9 presents a real embedded MCSoCs system design targeted for health monitoring in the elderly.
