Advanced Micro Devices (AMD) is to permit technology from opponent fragment planner ARM Holdings.
The US definite skeleton to increase an ARM-based processor to its P.C. chipsets to one side its own x86-based CPU (central estimate unit) and GPU (graphics estimate unit) technology.
The ARM-based core will be dedicated to gift safety features to guarantee activities such as online payments.
Analysts say this could be the commencement of an critical relationship.
Both firms vie against the world's largest semiconductor fragment maker, Intel.
AMD done the statement at its Fusion Developer Summit in Seattle.
The definite mentioned it expected to incorporate an ARM Cortex-A5 CPU to its chips for what it conditions "superthin" laptops from 2013, opposite chips for other mainstream computers in 2014, and over that in to servers.
The pierce is written to offer Personal Computer program developers access to ARM's Trustzone technology.
The safety underline usually lets granted program run on the additional core, creation it harder for hackers and malware to interrupt processes.
Potential uses include extended authentication systems for mobile banking, anti-virus program that is itself protected from attack, and digital rights administration program that can improved head off media files from being pirated.
"It runs the ethics in a really removed mood that is good protected from the bigger x86 environment," AMD's arch data officer, Mike Wolfe, told the BBC.
"Security is all a difficulty argument. What you wish to do is lower the amount of ethics that a safety function depends on since every 1,000 lines of ethics or so has a bug in it. Clearly when you are running hundreds of millions of lines of ethics the luck of having a bug is flattering high.
"So by shortening that mood and restricting the functions to well-defined properties you are shortening a lot of that risk."
ARM already offers use of Trustzone to developers essay apps for tablets and smartphones that use its fragment architecture, but this outlines a pierce in to a new market.
"We evidently see a direction of broader deployment of identical calm and applications on multi-part screens, and fluctuating this in to the x86 mood solves, what you believe, is an attention problem," mentioned Tom Lantzsch, ARM's senior manager clamp boss of corporate development.
The statement was deemed rarely poignant by Sergis Mushell, leading investigate researcher at the tech consultancy Gartner.
"Think about the number of smartphones and inscription gadgets out there," he said.
"If their apps are going to use a established methodology to do transactions, then having the same safety technology built in to PCs creates sense.
"For AMD this is about leveraging what is out there rsther than than perplexing to invent every segment of the wheel."
AMD was pithy that it moreover expected to incorporate the technology in to chipsets written for inscription computers - products where consumers put a reward on battery life. Mr Mushell referred to this could infer an chance for serve co-operation.
"AMD might moreover confirm to increase additional ARM cores to their existing technologies to emanate a new type of hybrid chipset," he added.
"But this definitely should not be seen as AMD giving up on its own x86 architecture."
