MIPS was a fabless semiconductor company, that is, they did not have the capability to fabricate integrated circuits. The chip set was initially fabricated for MIPS by Sierra Semiconductor and Toshiba. In December 1987, MIPS licensed Integrated Device Technology, LSI Logic, and Performance Semiconductor to also fabricate and market the R2000 ...

MIPS was a fabless semiconductor company, so the R3000 was fabricated by MIPS partners including Integrated Device Technology (IDT), LSI Logic, NEC Corporation, Performance Semiconductor, and others. It was fabricated in a 1.2 μm complementary metal–oxide–semiconductor (CMOS) process [1] with two levels of aluminium interconnect.
It had larger 16 KB primary caches, largely bug-free 64-bit operation, and support for a larger L2 cache. MIPS, now a division of Silicon Graphics (SGI) named MTI, designed the low-cost R4200, the basis for the even cheaper R4300i. A derivative of this microprocessor, the NEC VR4300, was used in the Nintendo 64 game console. [1]
[11] [failed verification] When MIPS II was introduced, MIPS was renamed MIPS I to distinguish it from the new version. [3]: 32 MIPS Computer Systems' R6000 microprocessor (1989) was the first MIPS II implementation. [3]: 8 Designed for servers, the R6000 was fabricated and sold by Bipolar Integrated Technology, but was a commercial failure.
Direct teleoperation of a Mars rover is impractical, as the round trip communication time between Earth and Mars ranges from 8 to 42 minutes and the Deep Space Network system is only available a few times during each Martian day . [1] Therefore, a rover command team plans, then sends, a sol of operational commands to the rover at one time. [1]
The Jazz systems were designed to partially comply with the Advanced RISC Computing (ARC) standard, and each used the ARC firmware to boot Windows NT. [1] Other operating systems were also ported to various Jazz implementations, such as RISC/os to the MIPS Magnum. The Jazz architecture includes: a MIPS R4000/R4400 or compatible microprocessor ...
Open MIPS architecture, for part of 2019 the specifications were free to use, royalty free, for registered MIPS developers. [67] OpenSPARC, in 2005, Sun released its Ultra Sparc documentation and specifications, under the GPLv2. LEON, an open source, radiation-tolerant implementation of the SPARC V8 instruction set (targeting space applications).
