Hyper Threading Technology in Hardware Architecture for Processor Efficiency Enhancement

Hyper-Threading Technology Architecture and Microarchitecture

Intel’s Hyper-Threading Technology brings the concept of simultaneous multi-threading to the Intel Architecture. Hyper-Threading Technology makes a single physical processor appear as two logical processors; the physical execution resources are shared and the architecture state is duplicated for the two logical processors. From a software or architecture perspective, this means operating system...

Hyper-Threading Technology on the Intel® XeonTM Processor Family for Servers

Pre-Silicon Validation of Hyper-Threading Technology

Hyper-Threading Technology delivers significantly improved architectural performance at a lower-thantraditional power consumption and die size cost. However, increased logic complexity is one of the trade-offs of this technology. Hyper-Threading Technology exponentially increases the micro-architectural state space, decreases validation controllability, and creates a number of new and interesti...

Media Applications on Hyper-Threading Technology

This paper characterizes selected workloads of multimedia applications on current superscalar architectures, and then it characterizes the same workloads on Intel HyperThreading Technology. The workloads, including video encoding, decoding, and watermark detection, are optimized for the Intel Pentium 4 processor. One of the workloads is even commercially available and it performs best on the Pe...

Task Scheduling Algorithm for Multicore Processor Systems with Turbo Boost and Hyper-Threading

In this paper, we propose a task scheduling algorithm for multiprocessor systems with Turbo Boost and HyperThreading technologies. The proposed algorithm minimizes the total computation time taking account of dynamic changes of the processing speed by the two technologies, in addition to the network contention among the processors. We constructed a clock speed model with which the changes of pr...
