Since MIPS I is a 32-bit architecture, loading quantities fewer than 32 bits requires the datum to be either sign-extended or zero-extended to 32 bits. The load instructions suffixed by "unsigned" perform zero extension; otherwise sign extension is performed.
Operating systems ported to the architecture include SGI's IRIX, Microsoft's Windows NT (through v4.0), Windows CE, Linux, FreeBSD, NetBSD, OpenBSD, UNIX System V, SINIX, QNX, and MIPS Computer Systems' own RISC/os. In the early 1990s, speculation occurred that MIPS and other powerful RISC processors would overtake the Intel IA-32 architecture.
The CPU IP cores comprising the MIPS Series5 ‘Warrior’ family are based on MIPS32 release 5 and MIPS64 release 6, and will come in three classes of performance and features: 'Warrior M-class': entry-level MIPS cores for embedded and microcontroller applications, a progression from the popular microAptiv family
The R3000 is a 32-bit RISC microprocessor chipset developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture (ISA). Introduced in June 1988, it was the second MIPS implementation, succeeding the R2000 as the flagship MIPS microprocessor. It operated at 20, 25 and 33.33 MHz.
The company licensed its 32- and 64-bit architectures as well as 32-bit cores. [75] The MIPS32 architecture is a high-performance 32-bit instruction set architecture (ISA) that is used in applications such as 32-bit microcontrollers, home entertainment, home networking devices and mobile designs.

The R2000 is a 32-bit microprocessor chip set developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture (ISA). Introduced in January 1986, it was, by a few months, the first commercial implementation of a RISC architecture.
A Toshiba R4000 microprocessor A IDT R4000 microprocessor MIPS R4000 die shot. The R4000 is a microprocessor developed by MIPS Computer Systems that implements the MIPS III instruction set architecture (ISA). Officially announced on 1 October 1991, it was one of the first 64-bit microprocessors and the first MIPS III implementation.
Intel A80386DX-20 CPU die image. The Intel 386, originally released as the 80386 and later renamed i386, is the third-generation x86 architecture microprocessor from Intel.It was the first 32-bit processor in the line, making it a significant evolution in the x86 architecture.
