Single Core Performance Still Important in Multicore Era

1.Background

For increasing in speed we see that recite of cores ar increasing in occurrent and future coming systems. We bemuse multicore systems but these multicores be not fully utilized. We investigate and capture that what is the best multicore configuration will be in future. We plead that, while enquiry on multi-core optimizations is valuable, improvements in single-core exertion via alter resource utilization are key to increasing murder and doing so with minimal impact on power consumption.

1.1 fit

To improve the performance of single core is the discipline of our work. The research will be focused on how to improve the performance of single core.

1.2 Application Area Addressed

In our research we are going to compare five models such as single-core, umpteen-core, tangled multicore, scalable homogeneous multicore and dynamic eachy configurable multicore are compared with apiece other, which are surprisingly unveils that single-core performance is a key to improve multicore performance.

2. contend and Problem

As the number of transistors on a chip increases, the flexibleness to determine a processor configuration also increases. The current trend is to use them to integrate multiple cores on a chip and we have almost 50 cores.



With such a large flexibility, we are confused what the best configuration is. How many cores should be integrated on a chip? Should each core have primary in-order pipelines or complex out-of-order ones? Should all cores are the same? These questions have to be answered.

3.Goal

Our research gain investigates what the best multicore configuration is. We also consider the advance in semiconductor technologies. We guess the best choice is different when the number of transistors increases. The best configuration must be different harmonize to applications executed on the processor. Hence, we analyze theoretically and use simple model to compare these variations in the research.
