Book excerpt: Abstract: "Sector caches use an address tag to identify a sector, and valid bits to indicate whether each subsector is present in the cache. This design permits a small number of tag bits to control a large number of data bytes in the cache. Such a design is useful for single level caches when cache sizes are small and/or when the optimal line sizes are small. Sector caches are most useful when small first-level tag arrays are used to control large second level cache data arrays. The problem with sector caches is that because of the constrained mapping between address tags and data array space, frequently many of the subsectors are not filled before the new sector is replaced. In this paper, we propose a new design, called the sector pool cache, in which subsectors may be shared between sectors, so that the cache data arrays are used much more efficiently. We evaluate this design using a large multiprogrammed workload to provide a more realistic test of the various cache designs. Our results show that the sector pool cache can be an attractive solution for a first level on-chip cache when used in conjunction with a regular second level off-chip sector cache. Such a design provides improved performance by allowing a larger fraction of first level cache bits to be used for data rather than for tags."

Download or read book A Primer on Compression in the Memory Hierarchy written by Somayeh Sardashti and published by Springer Nature. This book was released on 2022-05-31 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis lecture presents the current state-of-the-art in applying low-latency, lossless hardware compression algorithms to cache, memory, and the memory/cache link. There are many non-trivial challenges that must be addressed to make data compression work well in this context. First, since compressed data must be decompressed before it can be accessed, decompression latency ends up on the critical memory access path. This imposes a significant constraint on the choice of compression algorithms. Second, while conventional memory systems store fixed-size entities like data types, cache blocks, and memory pages, these entities will suddenly vary in size in a memory system that employs compression. Dealing with variable size entities in a memory system using compression has a significant impact on the way caches are organized and how to manage the resources in main memory. We systematically discuss solutions in the open literature to these problems. Chapter 2 provides the foundations of data compression by first introducing the fundamental concept of value locality. We then introduce a taxonomy of compression algorithms and show how previously proposed algorithms fit within that logical framework. Chapter 3 discusses the different ways that cache memory systems can employ compression, focusing on the trade-offs between latency, capacity, and complexity of alternative ways to compact compressed cache blocks. Chapter 4 discusses issues in applying data compression to main memory and Chapter 5 covers techniques for compressing data on the cache-to-memory links. This book should help a skilled memory system designer understand the fundamental challenges in applying compression to the memory hierarchy and introduce him/her to the state-of-the-art techniques in addressing them.

Book Synopsis Sector Cache Design and Performance by : Jeffrey B. Rothman
Download or read book Sector Cache Design and Performance written by Jeffrey B. Rothman and published by . This book was released on 1999 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: "The IBM 360/85, possibly the first commercially available CPU with a cache memory, used a cache with a sector design, by which the cache consisted of sectors (with address tags) and subsectors (or blocks, with valid bits). It rapidly became clear that superior performance could be obtained with the now familiar set-associative cache design. Because of changes in technology, the time has come to revisit the design of sector caches. Sector caches have the feature that large numbers of bytes can be tagged using relatively small numbers of tag bits, while still only transferring small blocks when a miss occurs. This suggests the use of sector caches for multilevel cache designs. In such a design, the cache tags can be placed at a higher level (e.g., on the processor chip) and the cache data array can be placed at a lower level (e.g., off-chip). In this paper, we present a thorough analysis of the design and use of uniprocessor sector caches. We start by creating a standard workload and then we calculate miss ratios for a wide range of sector cache designs. Those miss ratios are transformed into Design Target Miss Ratios, which are intended to be 'typical' miss ratios, suitable for use for design purposes ('design targets'). The miss ratios are then used to estimate performance, using typical timings, for a variety of one level and two level cache designs. We find that for single level caches, sector caches are seldom advantageous. For multilevel cache designs with small amounts of storage at the first level caches, as would be the case for small on-chip caches, sector caches can yield significant performance improvements. For multilevel designs with large amounts of first level storage, sector caches provide relatively small improvements."

Download or read book Microprocessor Architecture written by Jean-Loup Baer and published by Cambridge University Press. This book was released on 2009-12-07 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a comprehensive description of the architecture of microprocessors from simple in-order short pipeline designs to out-of-order superscalars. It discusses topics such as: • The policies and mechanisms needed for out-of-order processing such as register renaming, reservation stations, and reorder buffers • Optimizations for high performance such as branch predictors, instruction scheduling, and load-store speculations • Design choices and enhancements to tolerate latency in the cache hierarchy of single and multiple processors • State-of-the-art multithreading and multiprocessing emphasizing single chip implementations Topics are presented as conceptual ideas, with metrics to assess the performance impact, if appropriate, and examples of realization. The emphasis is on how things work at a black box and algorithmic level. The author also provides sufficient detail at the register transfer level so that readers can appreciate how design features enhance performance as well as complexity.

Download or read book Datacenter Design and Management written by Benjamin C. Lee and published by Springer Nature. This book was released on 2022-05-31 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: An era of big data demands datacenters, which house the computing infrastructure that translates raw data into valuable information. This book defines datacenters broadly, as large distributed systems that perform parallel computation for diverse users. These systems exist in multiple forms—private and public—and are built at multiple scales. Datacenter design and management is multifaceted, requiring the simultaneous pursuit of multiple objectives. Performance, efficiency, and fairness are first-order design and management objectives, which can each be viewed from several perspectives. This book surveys datacenter research from a computer architect's perspective, addressing challenges in applications, design, management, server simulation, and system simulation. This perspective complements the rich bodies of work in datacenters as a warehouse-scale system, which study the implications for infrastructure that encloses computing equipment, and in datacenters as distributed systems, which employ abstract details in processor and memory subsystems. This book is written for first- or second-year graduate students in computer architecture and may be helpful for those in computer systems. The goal of this book is to prepare computer architects for datacenter-oriented research by describing prevalent perspectives and the state-of-the-art.
