Editor’s Note: Personally I’m a sucker for anything to do with the 8051, not the least because I know the guy who designed the original article. On this basis I’m happy to post this article about Digital Core Design and their announcement of “The world’s most advanced 80C51 architecture.” I think the real news here is that the designers of this core will be available to answer questions at CeBIT. However, it would be remiss of me to neglect to mention that the little rascals already announced this back in January of this year, when it was covered in great detail by my illustrious colleague Collin Holland (see A quad-pipelined 16/32-bit microcontroller core).
The folks from Digital Core Design, a leading Intellectual Property (IP) Core provider and System-on-Chip (SoC) design house from Poland, have recently introduced what they enthusiastically describe as “The world’s most advanced 80C51 architecture.”
Thanks to the unique combination of the instruction set and an optimized architecture, the company says it has achieved results which are more than 56 times better than a standard 8051 and more than 70% more efficient, than the nearest competition.
“We’re proud to present the world’s fastest 80C51 CPU at CeBIT,” says Piotr Kandora, VCEO, Director of R&D in Digital Core Design. “That event is a heart of the digital world, that’s why we wanted to present our CPU there, to gain reliable information from IT and ICT professionals.”
Digital Core Design will be located at stand B46 in Hall 6, at the Polish National Pavilion, hosted by Ministry of Economy. DQ80251, world’s fastest 80C51 CPU will be presented from March 6 till March 10. There will be also a unique occasion to talk with the designers of the most efficient microprocessor on the first and the second day of the show. On Thursday, anyone can join official presentation of DQ80251 during ICT conference held by Ministry of Economy of the Republic of Poland.

The 8051 has come a long way as you say. I still have a bunch of old Intel 8031's in my drawer. These were "Romless" 8051s, where you used 2 of the ports as data/low address and high address for an EPROM. Leaving only two ports to actually use. Seemed a little pointless. Thank goodness for the Flash memory that MCUs have now.

The "point" was that you could then have a 64Kb addressable memory space - not available in "on-chip" memory of the day. 20 years ago worked on a 8031 based product that used a third port to page in memory banks to give up to 16Mb of storage. It was used to address a "huge" (and heavy) array of 32x28pin ceramic DIP flash chips for a digital audio announcing system for trains. With the advent of multi Gb iPod and MP3 players it all looks rather antique! The encoding required 4Kb of data for one second of speech-band audio; the 8031 would not have been capable of real-time decompression even if the algorithms existed.

Can not believe this!
With so many variations of 8-bit, 16-bit and 32-bit MCUs out there, why would anyone need a "fast" 80C51 MCU?
Then, what about software tools for it? Are there fancy new code development tools for that "fastest 80C51?
How about an emulator system for it?
Last but not least, where would they find code developers for it?
What would they tell a potential end user: "the projected life time of this new design using the fastest 80C51 is about 2 years, maybe 1 year!

There is a vast tool ecosystem for 8051s and the instruction set is unencumbered by patents. Chip companies don't like royalties so they will plop down an 8051 core if a speed demon isn't required. It sounds like the DQ80251 is designed for DCD's licensees to use with their other IP cores in their SoCs.
