Superscalar

The main idea of this article is “implementation of SMT concept in Intel processor” which is based on efficient use of limited amount of processor resources such that at OS and software level it is seems just like multiple processors are running multiple processes. It is less costly and more efficient. Sharing policy is also playing an important role in performance improvement. Background: In order to improve processor performance following traditional approaches like higher clock speeds, instruction-level

precision. On IVB, the ratio of performance between SP to DP is around 2, which is consistent with the SIMD width ratio of these two precisions. For KNC, the SIMD widths in SP and DP are 16 and 8 respectively, but a performance gap of 3 to 4 times in SP and DP is observed, which is well beyond the ratio of SIMD width. This is because the performance of where clauses for WS/DMMPs schemes on KNC is sensitive to the SIMD width as described in the section of SW26010 optimization. The wider the SIMD vectorization

certain fields, like graphics and scientific computing the amount can be very large while workloads such as cryptography may exhibit much less parallelism. Micro-architectural techniques that are used to exploit ILP include instruction pipelining, superscalar execution, register renaming, and so on. This paper will first access the basic concepts of ILP by exploring the ways of handling data,including the controlling data dependence and data hazards. Then we will talk about ways of how to expose ILP

Conditional branch predictor (CBP) is an essential component in the design of any modern deeply pipelined superscalar microprocessor architecture. In the recent past, many researchers have proposed varieties schemes for the design of the CBPs that claim to offer desired levels of accuracy and speed needed to meet the demand for the architectural design of multicore processors. Amongst various schemes in practice to realize the CBPs, the ones based on neural computing – i.e., artificial neural network

Task 1 The Control Unit There are two types of control unit which are hardwired and micro program where hardwired are for fixed architecture and are typically RISC and cost more than micro program because of the time required to design the circuits , but they are faster. Micro program control units are slower than hardwired but are easier and cheaper to implement as the instructions are stored in special control memory. The control unit controls all data going in, out and inside the CPU. The control

to speed up the processing process. All Intel PC products fall into this category. Pipelining, superscalar architecture, and branch prediction logic are currently technological buzzwords in the computer community presently. These technologies can be found in newer chips. Pipelining allows the chip to seek out new data while the old data is still being worked on (Wyant and Hammerstrom, 161). Superscalar architecture allows complex instructions to be broken down into smaller ones and then processed

Introduces the next generation of processors Yiming Xiao As the need for micro- architecture performance modeling power level will continue to work with future workload and performance requirements increase , the designer must make the right choices in defining the next generation of low-power microprocessors. In this article , I will mainly talk about the next generation of processors and processor used on smart phones and how they are designed in different situations. next generation processor

Abstract: This paper addresses about making a source code record, and assessing it on memory and execution utilizing multi2sim programming. Multi2Sim is a recreation system for CPU-GPU heterogeneous registering written in C. It incorporates models for superscalar, multithreaded, and multicore CPUs, and in addition GPU architectures. Graphics processing units (GPUs) have particular throughput arranged memory frameworks that are upgraded for spilling information. By growing the use of GPUs past representation

The never-ending comparative study between CISC and RISC Popa Emilia Ioana Department of Computer Science Polytechnic University of Bucharest emilia_ioana.popa@stud.acs.upb.ro Abstract. The comparative study between CISC (Complex Instruction Set Com-puter) and RISC (Reduced Instruction Set Computers) has been a well-known debate subject for many years. In the past, one significant development in com-puter processor technology was the RISC microprocessor. Many argued that RISC devices have offered
