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 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 Analysis of Static and Dynamic Memory Management Schemes in Embedded Systems Utilizing Software-managed Memory by : Muberra N. Akcaman

Download or read book Analysis of Static and Dynamic Memory Management Schemes in Embedded Systems Utilizing Software-managed Memory written by Muberra N. Akcaman. This book was released on 2015. Available in PDF, EPUB and Kindle. Book excerpt: The proposed work targets at data-intensive applications which involve processing of large data arrays within loop nests. Such applications frequently occur in image/video processing domains. The target architectures used in this thesis are both single-core and multi-core embedded systems. In multi-core architecture, each core has a local SPM; and each core accesses other SPMs (remote SPM) and an on-chip shared L2 memory with higher memory access latencies. All on-chip memories are software-managed. Both architectures have off-chip memory which holds the entire dataset. After profiling the embedded application, the dataset is divided into blocks and the access frequencies to these blocks are determined. The data mapping is done to L1 SPMs, L2 SPM and off-chip memory based on the access frequencies of data blocks. This process is done once at compile time in static memory allocation while it is repeated at the beginning of each execution phase at run-time in dynamic data allocation. The experimental results collected using data-intensive benchmark programs are presented in single and multi-core embedded architectural setups.
