Available in PDF, EPUB and Kindle. Book excerpt: In modern microprocessors, more memory hierarchy and larger caches are integrated on chip to bridge the performance gap between high-speed CPU core and low speed memory. Large set-associative L2 caches draw a lot of power, generate a large amount of heat, and reduce the overall yield of the chip. As a result, large power consumption of the cache memory system has become a new bottleneck for many microprocessors. In this research, we analyze the performance of a location cache which works with a low power L2 cache system implemented by the drowsy cache technique. A small direct-mapped location cache is added to the traditional L2 cache system. It caches the way location information for the L2 cache access. With this way location information, the L2 cache can be accessed as direct-mapped cache to save both dynamic and leakage power consumption. Detailed mathematical analysis of the location cache power saving rate is presented in this work. To evaluate the power consumption of the location cache system on real world workloads, both SPEC CPU2000 and SPEC CPU2006 benchmark applications are simulated with the reference input set. Simulation results demonstrate that the location cache system can save a significant amount of power for all benchmark applications in L1 write through policy, and save power for benchmark applications with high L1 miss rate in L1 write back policy.
Book Synopsis Location Cache Design and Performance Analysis for Chip Multiprocessors by : Jason Nemeth
Download or read book Location Cache Design and Performance Analysis for Chip Multiprocessors written by Jason Nemeth and published by . This book was released on 2008 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: As it becomes increasingly difficult to improve the performance of a microprocessor by simply increasing its clock speed, chip makers are looking towards parallelism in the form of Chip Multiprocessors (CMPs) to increase performance. Indeed, recent research at Intel suggests that chips with hundreds of cores are possible in the not-so-distant future. As the number of cores grows, so does the size of the cache systems required to allow them to operate efficiently. Caches have grown to consume a significant percentage of the power utilized by a processor. In this research, we extend the concept of a location cache to support CMP systems in combination with low-power L2 caches based upon the gated-ground technique. The combination of these two techniques allows for reductions in both dynamic and leakage power consumption. In this work we will present an analysis of the power savings provided by utilizing location caches in a CMP system. The performance of the cache system is evaluated by extending the capability of CACTI and Simics using the SPLASH-2 and ALPBench benchmark suites. These simulation results demonstrate that the utilization of location caches in CMP systems is capable of saving a significant amount of power over equivalent CMP systems that lack location caches.
Book Synopsis Design and Analysis of Location Cache in a Network-on-chip Based Multiprocessor System by : Divya Ramakrishnan
Download or read book Design and Analysis of Location Cache in a Network-on-chip Based Multiprocessor System written by Divya Ramakrishnan and published by . This book was released on 2009 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the direction of research to improve the performance of computing systems is focused toward chip multiprocessor (CMP) designs with multiple cores and shared caches integrated on a single chip. To meet the increased demand for data, large on-chip caches are being embedded on the chip, shared between the multiple cores. The traditional bus-based interconnect architectures are non-scalable for large caches and cannot support the higher cache demand from multiple cores, which motivates the design of a network-on-chip (NoC) interconnect structure for shared non-uniform cache architecture (NUCA). The concept of NUCA caches proposes the division of the cache into multiple banks connected by a switched network that can support the simultaneous transport of multiple packets. The larger on-chip cache designs also result in higher power consumption which is a serious concern as fabrication scales down to the nano-technologies. This research focuses on the implementation of the location cache design in a NoC-based NUCA system with multiple cores, in combination with low-leakage L2 cache based on the gated-ground technique. This system architecture helps to reduce the power of L2 cache along with the performance benefit of the on-chip network. The CMP cache system is implemented on a NoC-NUCA framework with a write-through coherency protocol. The features of CACTI and GEMS are extended to support a complete power and performance estimation of the system. A full-system simulation is performed on scientific and multimedia workloads to characterize the NoC-based system. An analysis of the power and performance of the proposed system is presented in comparison with the traditional cache structure in different configurations. The simulation results show that the NoC-based system with the location cache results in significantly saving the energy of the cache system over the traditional bus-based system in any configuration and also the NoC-based system without a location cache. The system also provides better performance compared to a bus-based system, emphasizing the need to shift to a network-based cache interconnect design which can scale to a large number of cores.
Book Synopsis Analysis of Cache Performance for Operating Systems and Multiprogramming by : Agarwal
Download or read book Analysis of Cache Performance for Operating Systems and Multiprogramming written by Agarwal and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: As we continue to build faster and fast. er computers, their performance is be coming increasingly dependent on the memory hierarchy. Both the clock speed of the machine and its throughput per clock depend heavily on the memory hierarchy. The time to complet. e a cache acce88 is oft. en the factor that det. er mines the cycle time. The effectiveness of the hierarchy in keeping the average cost of a reference down has a major impact on how close the sustained per formance is to the peak performance. Small changes in the performance of the memory hierarchy cause large changes in overall system performance. The strong growth of ruse machines, whose performance is more tightly coupled to the memory hierarchy, has created increasing demand for high performance memory systems. This trend is likely to accelerate: the improvements in main memory performance will be small compared to the improvements in processor performance. This difference will lead to an increasing gap between prOCe880r cycle time and main memory acce. time. This gap must be closed by improving the memory hierarchy. Computer architects have attacked this gap by designing machines with cache sizes an order of magnitude larger than those appearing five years ago. Microproce880r-based RISe systems now have caches that rival the size of those in mainframes and supercomputers.

Download or read book Heterogeneous Computing written by Mohamed Zahran and published by Morgan & Claypool. This book was released on 2019-05-29 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: If you look around you will find that all computer systems, from your portable devices to the strongest supercomputers, are heterogeneous in nature. The most obvious heterogeneity is the existence of computing nodes of different capabilities (e.g. multicore, GPUs, FPGAs, ...). But there are also other heterogeneity factors that exist in computing systems, like the memory system components, interconnection, etc. The main reason for these different types of heterogeneity is to have good performance with power efficiency. Heterogeneous computing results in both challenges and opportunities. This book discusses both. It shows that we need to deal with these challenges at all levels of the computing stack: from algorithms all the way to process technology. We discuss the topic of heterogeneous computing from different angles: hardware challenges, current hardware state-of-the-art, software issues, how to make the best use of the current heterogeneous systems, and what lies ahead. The aim of this book is to introduce the big picture of heterogeneous computing. Whether you are a hardware designer or a software developer, you need to know how the pieces of the puzzle fit together. The main goal is to bring researchers and engineers to the forefront of the research frontier in the new era that started a few years ago and is expected to continue for decades. We believe that academics, researchers, practitioners, and students will benefit from this book and will be prepared to tackle the big wave of heterogeneous computing that is here to stay.

Available in PDF, EPUB and Kindle. Book excerpt: Theimportanceofsafetyandsecurityisgrowingsteadily.Safetyisaqualityc- racteristic that traditionally has been considered to be important in embedded systems, and security is usually an essential property in business applications. There is certainly a tendency to use software-based solutions in safety-critical applications domains, which increases the importance of safety engineering te- niques. These include modelling and analysis techniques as well as appropriate processes and tools. And it is surely correct that the amount of con?dential data that require protection from unauthorized access is growing. Therefore, security is very important. On the one hand, the traditional motivations for addressing safety and security still exist, and their relevance has improved. On the other hand, safety and security requirements occur increasingly in the same system. At present, many software-based systems interact with technical equipment and they communicate, e.g., with users and other systems. Future systems will more and more interact with many other entities (technical systems, people, the en- ronment). In this situation, security problems may cause safety-related failures. It is thus necessary to address safety and security. It is furthermore required to take into account the interactions between these two properties.
