MANHASSET, N.Y. IP licensing company Acacia Research Corp. said Tuesday (April 19) that its Microprocessor Enhancement Corp. subsidiary has filed a patent infringement lawsuit in California against Intel Corp. and Texas Instruments Inc.
The suit was filed in U.S. District Court for the Central District of California, which includes Los Angeles and surrounding counties.
The lawsuit by Acacia (Newport Beach, Calif.) alleges patent infringement by Intel's Itanium line of microprocessors, and certain series of digital signal processors sold by Texas Instruments.
Microprocessor Enhancement's patent generally relates to an architecture employed in advanced pipeline processors. This architecture allows for conditional execution of processor instructions, and a later determination of whether the instructions executed should be written back to memory.
By conditionally executing instructions in this architecture, significant improvements in processor speed can be achieved. Certain pipelined processor makers are adopting this processing method to improve processor speed.
