Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: 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

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.

Writing programs for embedded systems can be very different from writing programs for general-purpose computers. Embedded systems may have resource limitations such as processing and battery power, memory, input/output capabilities and limited operating system functionality. They may have real-time and safety considerations that need to be met. In addition, developing for multicore embedded systems requires the programming language to provide concurrency support. In this chapter, special emphasis is placed on demonstrating features of each language that support efficient development on multicore embedded systems.

Available in PDF, EPUB and Kindle. Book excerpt: Synchronization hardware is a fundamental requirement for concurrent software. Ultimately, software depends upon strong guarantees for atomicity, which can only be provided by hardware. Fortunately, hardware can provide a simple but powerful programming interface to higher-level software using only a few synchronization primitives. These few primitives can support a surprisingly broad range of capabilities in software. Yet, even with hardware support to ensure functional correctness, there is an unavoidable performance overhead to pay for synchronization. In recent years, hardware designed to replace precise locking with speculative lock avoidance (e.g., lock-free programming) has begun to emerge. This chapter provides an in-depth look at the lowest level hardware/software interface for synchronization, along with explanations of how the underlying hardware ensures atomicity, and considerations related to weakly consistent memory models. This is complemented with a discussion of various lock avoidance techniques.

Available in PDF, EPUB and Kindle. Book excerpt: An operating system (OS) is an important component of most computer systems. At a minimum, the OS is responsible for managing tasks and resources. This becomes more challenging in a multicore environment, where multiple tasks can execute concurrently and must vie for shared resources. So the OS configuration is a critical consideration when building a multicore system. This chapter describes the different ways one or more OSes can be instantiated in multicore systems, along with many of the more critical controls that architects and programmers have for customizing the behavior of the OS. Included is a discussion of some of the debugging tools that are often shipped with OSes.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Synchronization is the key mechanism used within software applications to safely and efficiently leverage today’s multicore hardware architectures. This chapter aims to build your expertise and knowledge in software synchronization, from the needs behind synchronization to the possible solutions to implement synchronization. The target reader of this chapter is the embedded multicore software developer, along with the tester, project manager, and customer, in order to educate the entire software development team about the technology and the issues. Problems that occur when synchronization is not used, or when it is used badly, are considered. An in-depth look at how to achieve synchronization and also specific conditions that require synchronization are the primary focus of this chapter. Specific synchronization support for different languages, along with design patterns useful for architecting of a synchronized system, are discussed. The chapter wraps up looking at side-effects (good and bad) and problems encountered when writing synchronization code, as well as hardware and operating system effects on synchronization.

The implications of concurrency both for faster program execution and for mind-numbing debugging are at the same time profound and subtle. Because everything that’s important about multicore relates to concurrency, this chapter tackles the topic at a high level. It presents some of the obvious aspects of attempts to run multiple tasks at the same time, but also introduces the many complications and difficulties that accompany thel benefits.

Book excerpt: To satisfy the higher requirements of digitally converged embedded systems, this book describes heterogeneous multicore technology that uses various kinds of low-power embedded processor cores on a single chip. With this technology, heterogeneous parallelism can be implemented on an SoC, and greater flexibility and superior performance per watt can then be achieved. This book defines the heterogeneous multicore architecture and explains in detail several embedded processor cores including CPU cores and special-purpose processor cores that achieve highly arithmetic-level parallelism. The authors developed three multicore chips (called RP-1, RP-2, and RP-X) according to the defined architecture with the introduced processor cores. The chip implementations, software environments, and applications running on the chips are also explained in the book. Provides readers an overview and practical discussion of heterogeneous multicore technologies from both a hardware and software point of view; Discusses a new, high-performance and energy efficient approach to designing SoCs for digitally converged, embedded systems; Covers hardware issues such as architecture and chip implementation, as well as software issues such as compilers, operating systems, and application programs; Describes three chips developed according to the defined heterogeneous multicore architecture, including chip implementations, software environments, and working applications.

Available in PDF, EPUB and Kindle. Book excerpt: Unlike general-purpose computing systems, multicore embedded systems are designed with a specific application in mind. The memory access patterns for the application can be used to customize the memory architecture of the device. This chapter presents a synopsis of memory types and architecture commonly used in multicore embedded systems. It examines the many trade-offs that can be considered when designing the memory architecture. It considers factors such as whether the memory should be shared or distributed among the multiple cores; will the cores benefit from memory cache and what should the cache configuration be; is there a cache coherency protocol used; should there be other memory types on the device such as scratch pad SRAMs and eDRAMs; does the device use a DMA for memory transfers, and other factors. It provides guidance to the embedded system designers to tailor the memory architecture to their needs.
