asynchronous - 无时钟计算机芯片发生了什么？

Question

几年前，“下一件大事”是无时钟计算机。其背后的想法是，如果没有时钟，处理器的运行速度会显着加快。

那是那时，现在是现在，我找不到任何关于它是如何进行的或这个想法是否失败的信息......

有人知道吗？

Answer 1

这是an article from a few years ago这是对技术的热衷，但我认为可以在下面的引文中找到答案:

Why, for example, did Intel scrap its asynchronous chip? The answer is that although the chip ran three times as fast and used half the electrical power as clocked counterparts, that wasn't enough of an improvement to justify a shift to a radical technology. An asynchronous chip in the lab might be years ahead of any synchronous design, but the design, testing and manufacturing systems that support conventional microprocessor production still have about a 20-year head start on anything that supports asynchronous production. Anyone planning to develop a clockless chip will need to find a way to short-circuit that lead.

"If you get three times the power going with an asynchronous design, but it takes you five times as long to get to the market—well, you lose," says Intel senior scientist Ken Stevens, who worked on the 1997 asynchronous project. "It's not enough to be a visionary, or to say how great this technology is. It all comes back to whether you can make it fast enough, and cheaply enough, and whether you can keep doing it year after year."
