AMD, Intel others sued over CPU execution

Posted

ATLANTA, GEORGIA - Chip firms Intel and AMD have found themselves in the company of seven other semiconductor giants and are being sued by a Georgia company for allegedly infringing a patent.


The other defendants in the case, filed at the end of last week in a district court in Atlanta are Broadcom, Freescale, Infineon, IBM, ST Microelectronics, Sun Microsystems and Texas Instruments,


Optimum Processing Solutions LLC claims that the companies have breached a US patent, 5,115,497 - issued on the 19th of May 1992 and called Optically intraconnected computer employing dynamically reconfigurable holographic optical element.


Optimum alleges that this patent optimizes the simultaneous operation of execution elements in a multiple instruction environment. One feature of the patent, it's claimed allows the element selection logic to accept dynamic inputs designating changes in the operating environment of the computer, and changes the elements that execute each instruction to optimize execution depending on the current dynamic conditions.


The court filing then describes how the various defendants' products infringe its patent. Allegedly.


AMD's Turion and Phenom use a similar system to the patent; Broadcom's BCM1480 and BCM1455 also infringe the patents. Freescale's i.mx51 and PowerQuic III; Infineon's XC2000, XE166 and XC166; Intel's Quad Core and Core 2 Duo; IBM's Cell Chip; ST Micro's ST140; Sun's Ultra SPARC IV+ and TI's Arm Cortex A8 and ARM Cortex A9 all infringe the patents, alleges Optimum.


It's alleged that Intel knows all about this patent and Caltech provided Intel with a list of patents including the Optimum patent.


Needless to say, Optimum wants damages for breaches of the patent, and three times the damage based on "Intel's willful ingringement and/or bad faith". The plaintiff wants a jury trial.
