Book Synopsis Memory Allocation Problems in Embedded Systems by : Maria Soto

Download or read book Memory Allocation Problems in Embedded Systems written by Maria Soto. This book was released on 2013-01-24. Available in PDF, EPUB and Kindle. Book excerpt: Embedded systems are everywhere in contemporary life and are supposed to make our lives more comfortable. In industry, embedded systems are used to manage and control complex systems (e.g. nuclear power plants, telecommunications and flight control) and they are also taking an important place in our daily activities (e.g. smartphones, security alarms and traffic lights). In the design of embedded systems, memory allocation and data assignment are among the main challenges that electronic designers have to face. In fact, they impact heavily on the main cost metrics (power consumption, performance and area) in electronic devices. Thus designers of embedded systems have to pay careful attention in order to minimize memory requirements, thus improving memory throughput and limiting the power consumption by the system’s memory. Electronic designers attempt to minimize memory requirements with the aim of lowering the overall system costs. A state of the art of optimization techniques for memory management and data assignment is presented in this book.

Book Synopsis Dynamic Memory Management for Embedded Systems by : David Atienza Alonso

Download or read book Dynamic Memory Management for Embedded Systems written by David Atienza Alonso. This book was released on 2014-09-19. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a systematic and unified methodology, including basic principles and reusable processes, for dynamic memory management (DMM) in embedded systems. The authors describe in detail how to design and optimize the use of dynamic memory in modern, multimedia and network applications, targeting the latest generation of portable embedded systems, such as smartphones. Coverage includes a variety of design and optimization topics in electronic design automation of DMM, from high-level software optimization to microarchitecture-level hardware support. The authors describe the design of multi-layer dynamic data structures for the final memory hierarchy layers of the target portable embedded systems and how to create a low-fragmentation, cost-efficient, dynamic memory management subsystem out of configurable components for the particular memory allocation and de-allocation patterns for each type of application. The design methodology described in this book is based on propagating constraints among design decisions from multiple abstraction levels (both hardware and software) and customizing DMM according to application-specific data access and storage behaviors.

Book Synopsis Optimization Methods for the Memory Allocation Problems in Embedded Systems by : María Consuelo Soto Lima

Download or read book Optimization Methods for the Memory Allocation Problems in Embedded Systems written by María Consuelo Soto Lima. This book was released on 2011. Available in PDF, EPUB and Kindle. Book excerpt: Memory allocation in embedded systems is one of the main challenges that electronic designers have to face. This part, rather difficult to handle is often left to the compiler with which automatic rules are applied. Nevertheless, a carefully tailored allocation of data to memory banks may lead to great savings in terms of running time and energy consumption. This thesis addresses various versions of the memory allocation problem. At each version the problem's complexity increases, i.e., the number of constrains increases. The number of memory banks, bank capacities, sizes and number of accesses of data structures, and the conflicting data structures at each time interval are the main constrains handled in the memory allocationproblems. In this work we present an ILP formulation and some metaheuristics implemented for each problem version. We also assess ourmetaheuristics with the exact methods and other literature metaheuristics with the aim of highlighting what makes the success of metaheuristics for these problems.
