I have an asynchronous CPU cluster on my desk right now (a pair of GA144s). The performance spread isn't actually very dramatic; just a few percent. After all, the foundries aim for consistency so that synchronous devices get good yiel

Regardless of the Nyuzi's merits, that demo is unimpressive. We (RenderMorphics and then Microsoft D3D) were happily spinning teapots on 50 MHz 486s, significantly faster than that.

Yes, upon being insulted the best response is to avoid being insulted. The idea goes back a long way. http://boingboing.net/2010/10/29/twenty-first-century-3.html

Yes, the PDP-11 instruction set makes null-terminated strings especially efficient. Strcpy() is 3 instructions per character, for example. The PDP-11 features that make this possible are (1) post increment addressing and (2) MOVE instructio

I make chips for a living, and if I had screwed up this badly I would fully expect to be fired. Being fired for incompetence is much more demeaning than gentle mockery by people writing a workaround.

Since everything is always getting worse, at some point in the future we will look back at the clickbait nonsense of 2015 with genuine nostalgia. "Those were the days of real content. Before it all turned to crap" Shudder.

Instead of that complicated minute/day/week/year data retention scheme, why not just randomly replace an entry in a fixed-size store? So the probability of a datum being in the store is inversely proportional to the log of i

I write Forth code for tiny microcontrollers that are embedded in ASICs. They are ROM-based, and have to work first time. Size is a few hundred bytes, so C is out of question.

FWIW I have a 16-bit version of the J1 CPU running on this FPGA; it uses about 75% of the available gates.
