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.

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.

Download or read book Analysis of Static and Dynamic Memory Management Schemes in Embedded Systems Utilizing Software managed Memory written by Muberra N. Akcaman and published by . This book was released on 2015 with total page 106 pages. 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.

Download or read book Dynamic Memory Management for Embedded Real time Multiprocessor System on a chip written by Mohamed A. Shalan and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The aggressive evolution of the semiconductor industry - smaller process geometries, higher densities, and greater chip complexity - has provided design engineers the means to create complex, high-performance System-on-a-Chip (SoC) designs. Such SoC designs typically have more than one processor and huge (tens of Mega Bytes) amount of memory, all on the same chip. Dealing with the global on-chip memory allocation/deallocation in a dynamic yet deterministic way is an important issue for upcoming billion transistor multiprocessor SoC designs. To achieve this, we propose a memory management hierarchy we call Two-Level Memory Management. To implement this memory management scheme which presents a shift in the way designers look at on-chip dynamic memory allocation - we present the System-on-a-Chip Dynamic Memory Management Unit (SoCDMMU) for allocation of the global on-chip memory, which we refer to as Level Two memory management (Level One is the management of memory allocated to a particular on-chip Processing Element, e.g., an operating system's management of memory allocated to a particular processor). In this way, processing elements (heterogeneous or non-heterogeneous hardware or software) in an SoC can request and be granted portions of the global memory in a fast and deterministic time. A new tool is introduced to generate a custom optimized version of the SoCDMMU hardware. Also, a real-time operating system is modified support the new proposed SoCDMMU. We show an example where shared memory multiprocessor SoC that employs the Two-Level Memory Management and utilizes the SoCDMMU has an overall average speedup in application transition time as well as normal execution time.

Download or read book Custom Memory Management Methodology written by Francky Catthoor and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main intention of this book is to give an impression of the state-of-the-art in system-level memory management (data transfer and storage) related issues for complex data-dominated real-time signal and data processing applications. The material is based on research at IMEC in this area in the period 1989- 1997. In order to deal with the stringent timing requirements and the data dominated characteristics of this domain, we have adopted a target architecture style and a systematic methodology to make the exploration and optimization of such systems feasible. Our approach is also very heavily application driven which is illustrated by several realistic demonstrators, partly used as red-thread examples in the book. Moreover, the book addresses only the steps above the traditional high-level synthesis (scheduling and allocation) or compilation (traditional or ILP oriented) tasks. The latter are mainly focussed on scalar or scalar stream operations and data where the internal structure of the complex data types is not exploited, in contrast to the approaches discussed here. The proposed methodologies are largely independent of the level of programmability in the data-path and controller so they are valuable for the realisation of both hardware and software systems. Our target domain consists of signal and data processing systems which deal with large amounts of data.
