Lawsuit alleges infringement in core features of Dell's computers and Intel's microprocessors MicroUnity Systems Engineering Inc. has filed a lawsuit against Dell Inc. and Intel Corp., alleging infringement of seven of its multimedia processing and computer architecture patents, it said Friday.The lawsuit, filed Friday in the U.S. District Court in Marshall, Texas, alleges that core features of Dell’s computer systems and Intel’s microprocessors infringe the patents. Infringing features include hyperthreading features in Intel’s latest microprocessors and Dell’s latest computer systems, and the Streaming SIMD (Single Instruction Multiple Data) Extension (SSE) and SSE2 multimedia extensions to Intel microprocessors, MicroUnity said.Neither Dell nor Intel was immediately able to comment. MicroUnity was set up in 1988. One of the founders, Chief Executive Officer John Moussouris, was previously co-founder of MIPS Computer Systems Inc., now known as MIPS Technologies Inc. That company developed the MIPS (Microprocessor without interlocked pipeline stages) RISC (reduced instruction set computing) microprocessor architecture. Technology Industry
