Optimal Resource Allocation with MultiAmdahl
Found in: Computer
By Tsahee Zidenberg,Isaac Keslassy,Uri Weiser
Issue Date:July 2013
pp. 70-77
The MultiAmdahl framework provides an optimal resource allocation in heterogeneous multiprocessor chips, given a model of the workload and of the performance of each on-chip component.
 
MultiAmdahl: How Should I Divide My Heterogenous Chip?
Found in: IEEE Computer Architecture Letters
By Tsahee Zidenberg,Isaac Keslassy,Uri Weiser
Issue Date:July 2012
pp. 65-68
Future multiprocessor chips will integrate many different units, each tailored to a specific computation. When designing such a system, a chip architect must decide how to distribute the available limited system resources, such as area and power, among all...
 
Nahalal: Cache Organization for Chip Multiprocessors
Found in: IEEE Computer Architecture Letters
By Zvika Guz, Idit Keidar, Avinoam Kolodny, Uri Weiser
Issue Date:January 2007
pp. 21-24
This paper addresses cache organization in Chip Multiprocessors (CMPs). We show that in CMP systems it is valuable to distinguish between shared data, which is accessed by multiple cores, and private data accessed by a single core. We introduce Nahalal, an...
 
Correlated Load-Address Predictors
Found in: Computer Architecture, International Symposium on
By Michael Bekerman, Stephan Jourdan, Ronny Ronen, Gilad Kirshenboim, Lihu Rappoport, Adi Yoaz, Uri Weiser
Issue Date:May 1999
pp. 0054
As microprocessors become faster, the relative performance cost of memory accesses increases. Bigger and faster caches significantly reduce the absolute load-to-use time delay. However, increase in processor operational frequencies impairs the relative loa...

The MMX TM Technology extension to the Intel Architecture is designed to accelerate multimedia and communications software running on Intel Architecture processors. The technology introduces new data types and instructions that implement a SIMD architectur...
 
Peripheral Memory: a Technique for Fighting Memory Bandwidth Bottleneck
Found in: IEEE Computer Architecture Letters
By Leonid Azriel,Avi Mendelson,Uri Weiser
Issue Date:May 2014
pp. 1
Memory bottleneck has always been a major cause for limiting the performance of computer systems. While in the past latency was the major concern, today, lack of bandwidth becomes a limiting factor as well, as a result of exploiting more parallelism with t...
 
Generalized MultiAmdahl: Optimization of Heterogeneous Multi-Accelerator SoC
Found in: IEEE Computer Architecture Letters
By Amir Morad,Tomer Y. Morad,Yavits Leonid,Ran Ginosar,Uri Weiser
Issue Date:January 2014
pp. 1-1
Consider a workload comprising a consecutive sequence of program execution segments, where each segment can either be executed on general purpose processor or offloaded to a hardware accelerator. An analytical optimization framework based on MultiAmdhal fr...
 
Multiple clock and voltage domains for chip multi processors
Found in: Proceedings of the 42nd Annual IEEE/ACM International Symposium on Microarchitecture (Micro-42)
By Avi Mendelson, Efraim Rotem, Ran Ginosar, Uri Weiser
Issue Date:December 2009
pp. 459-468
Power and thermal are major constraints for delivering compute performance in high-end CPU and are expected to be so in the future. CMP is becoming important by delivering more compute performance within the power constraints. Dynamic Voltage and Frequency...
     
Intel MMX for multimedia PCs
Found in: Communications of the ACM
By Alex Peleg, Sam Wilkie, Uri Weiser
Issue Date:January 1988
pp. 24-38
The online Risks Forum has long been a hotbed for discussions of the relative merits of openness relating to the dissemination of knowledge about security vulnerabilities. The debate has now been rekindled, and is summarized here.
