New 64-bit Microprocessor Unveiled

October 2, 1991

SAN FRANCISCO (AP) _ In an attempt to set a new industry standard for microprocessors, MIPS Computer Systems Inc. unveiled a 64-bit R4000 RISC chip on Tuesday.

Robert C. Miller, MIPS chairman and chief executive officer, praised his chip as the highest performing, single-chip microprocessor available.

″The tremendous power contained in the single chip R4000 will give customers innovative software and hardware choices they never dreamed possible,″ Miller said.

MIPS officials announced the new microprocessor with the five semiconductor firms making the chip: LSI Logic, Integrated Device Technology, Inc., NEC Electronics, Performance Semiconductor and Siemans Components, Inc.

MIPS intends to make the R4000 the microprocessor standard for the ACE consortium, according to MIPS spokeswoman Joanne Hasegawa.

″We intend to use this as the microprocessor of choice because it is so advanced,″ Hasegawa said.

ACE, or the Advanced Computer Environments consortium, formed in April, includes Compaq Computer Corp., Digital Equipment Corp., Microsoft Corp. and Mips Computer Systems Inc. The group is attempting to set the standard for advanced PC and workstation architectures.

″At no other time has there been a next-generation microprocessor available from multiple sources,″ Hasegawa said.

The R4000 is expected to be commercially available in mid-1992.
