Book Synopsis Software Engineering for Embedded Systems by : Mike Brogioli
Download or read book Software Engineering for Embedded Systems written by Mike Brogioli and published by Elsevier Inc. Chapters. This book was released on 2013-04-01 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optimization metrics for compiled code are not always measured in resulting execution clock cycles on the target architecture. Consider a modern cellular telephone or wireless device which may download executables over a wireless network connection or backhaul infrastructure. In such cases, it is often advantageous for the compiler to reduce the size of the compiled code which must be downloaded to the wireless device. By reducing the size of the code needed to be downloaded, savings are achieved in terms of bandwidth required for each wireless point of download. Optimization metrics such as the memory system performance of compiled code are other metrics which are often important to developers. These are metrics correlated to the dynamic run-time behavior of not only the compiled code on the target processor, but also the underlying memory system, caches, DRAM and buses, etc. By efficiently arranging the data within the application or, more specifically, the order in which data and corresponding data structures are accessed by the application dynamically at run-time, significant performance improvements can be gained at the memory-system level. In addition, vectorizing compilers can also improve performance due to spatial locality of data when SIMD instruction sets are present and varying memory-system alignment conditions are met.
Book Synopsis Utilization Control and Optimization of Real-Time Embedded Systems by : Xue Liu
Download or read book Utilization Control and Optimization of Real-Time Embedded Systems written by Xue Liu and published by . This book was released on 2015-09-23 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-time embedded systems have been widely deployed in mission-critical applications, such as avionics mission computing, highway traffic control, remote patient monitoring, wireless communications, navigation, etc. These applications always require their real-time and embedded components to work in open and unpredictable environments, where workload is volatile and unknown. In order to guarantee the temporal correctness and avoid severe underutilization or overload, it is of vital significance to measure, control, and optimize the processor utilization adaptively. A key challenge in this mission is to meet real-time requirements even when the workload cannot be accurately characterized a priori. Traditional approaches of worst-case analysis may cause underutilization of resources, while Model Predictive Control (MPC) based approaches may suffer severe performance deterioration when large estimation errors exist. To address this challenging problem and provide better system performance, we have developed several important online adaptive optimal control approaches based on advanced control techniques. Our approaches adopt Recursive Least Square (RLS) based model identification and Linear Quadratic (LQ) optimal controllers to guarantee that the systems are neither overloaded, nor underloaded. These proposed approaches, as well as the associated tools, can quickly adapt to volatile workload changes to provide stable system performance. To minimize the impact of modeling errors, we adopt the Adaptive Critic Design (ACD) technique and develop an improved solution that requires little information of the system model. To deal with the discrete task rates, we further propose to utilize the frequency scaling technique to assist the utilization control and optimization.

Book Synopsis Code Optimization Techniques for Embedded Processors by : Rainer Leupers
Download or read book Code Optimization Techniques for Embedded Processors written by Rainer Leupers and published by Springer. This book was released on 2010-10-29 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The building blocks of today's and future embedded systems are complex intellectual property components, or cores, many of which are programmable processors. Traditionally, these embedded processors mostly have been pro grammed in assembly languages due to efficiency reasons. This implies time consuming programming, extensive debugging, and low code portability. The requirements of short time-to-market and dependability of embedded systems are obviously much better met by using high-level language (e.g. C) compil ers instead of assembly. However, the use of C compilers frequently incurs a code quality overhead as compared to manually written assembly programs. Due to the need for efficient embedded systems, this overhead must be very low in order to make compilers useful in practice. In turn, this requires new compiler techniques that take the specific constraints in embedded system de sign into account. An example are the specialized architectures of recent DSP and multimedia processors, which are not yet sufficiently exploited by existing compilers.
