On the top500.org list of the world's fastest computers, the bottom-ranked machine has a performance of 851 gigaflops.

这个星期讨论的原型细胞芯片的主频将高达256G，比现在最快的桌面台式机性能高出十倍左右，因此细胞芯片被广泛地称为&芯片上的超级计算机&，这么说有点夸张，但不算过分，在top500.org世界最快计算机名单上，最慢的计算机的性能是851G，由仅仅四个细胞芯片构成的计算机的性能将轻易超过这台机器。

The prototype Cell being discussed this week runs at 256 gigaflops (a flop—one "floating-point" operation per second—is a measure of how fast a processor can perform the individual operations of digital arithmetic that all computing ultimately boils down to). A speed of 256 gigaflops is around ten times the performance of the chips found in the fastest desktop PCs today; the Cell is thus widely referred to as a "supercomputer on a chip", which is an exaggeration, but not much of one. On the top500.org list of the world's fastest computers, the bottom-ranked machine has a performance of 851 gigaflops. A machine based on only four Cell chips would easily outrank this.

This paper takes the advantages of FPGA"s regular routing resources to judge the crucialities of each net to be routed, aims at determining the routing order,which greatly helps to improve the routability based on area-constrained and reduce time cost at the same time. When taking nets" high demand for delay into account, this paper takes full use of mid-length segments.This paper builds an NCJ algorithm routing model, then showes a router consists of NCJ global router and SEGA detailed router which is implemented by C++ program language.

本文充分利用FPGA芯片本身具有的固定的规则的布线资源这一特点，提出在对每一个线网布线之前将待布的线网进行关键性分析，再根据关键性大小对关键性相对大的线网进行布线，即NCJ算法；此算法有效地在保证芯片性能的同时，提高了布线资源的利用率，同时考虑到深亚微米时布线时延是影响芯片性能的一个重要因素，因此充分利用芯片的中长线布线资源以减少通过编程开关的几率。
