There are two versions, designed in 1.2 micron and 0.8micron CMOS. The 1.2 micron version was fabricated in 1993 and consists of around110,000 transistors on a 10mm x 10mm die. Here is a <!WA4><a href="http://www.cs.washington.edu/research/projects/lis/chaos/www/chipphoto.gif"> photo </a> of the 1.2 micron version. The 0.8 micron version was designed in 1994 as a revision of the first chip, but was not fabricated.<p>The chips are designed using a combination of standard cells and custom logic.There are five input buffers, five output buffers, and five multiqueue slots,each implemented with a 20-word by 16-bit fifo. These are connected by two crossbarsin a single unit. <p>The 1.2 micron chip was fabricated and operated (nearly) correctly up to speeds of 30 MHz, shortof its designed 66MHz operation. The 0.8 micron version included a redesign of the channel logic andfifos, as well as the clocking scheme. This version operates at 170 MHz in simulations, but hasnot been fabricated.<p>More details are available in the <!WA5><a href="http://www.cs.washington.edu/research/projects/lis/chaos/www/abstracts/chip.html"><em> VLSI '93 </em> </a> paper and in <!WA6><a href="http://www.cs.washington.edu/research/projects/lis/chaos/www/abstracts/boldingphd.html">Bolding's dissertation </a>.<hr><!WA7><a href="http://www.cs.washington.edu/research/projects/lis/chaos/www/chaos.html"><!WA8><img src=http://www.cs.washington.edu/research/projects/lis/chaos/www/chaos.xbm></a> Back to the Chaotic Routing Home Page <p></body><p><address>kwb@cs.washington.edu</address></html>⌨️ 快捷键说明
