The MIPS architecture has several optional extensions: MIPS-3D, a simple set of floating-point SIMD instructions dedicated to 3D computer graphics; [6] MDMX (MaDMaX), a more extensive integer SIMD instruction set using 64-bit floating-point registers; MIPS16e, which adds compression to the instruction stream to reduce the memory programs ...
This MIPS project grew out of a graduate course by John L. Hennessy, produced a functioning system in 1983, and could run simple programs by 1984. [25] The MIPS approach emphasized an aggressive clock cycle and the use of the pipeline, making sure it could be run as "full" as possible. [25]
The core R2000 chip executed all non-floating-point instructions with a simple short pipeline. This chip also controlled the external code and data caches, made of fast standard SRAM chips organized with direct indexing and one-cycle read latency. The R2000 chip contained a small translation lookaside buffer for mapping virtual memory addresses ...
The MIPS architecture provides a specific example for a machine code whose instructions are always 32 bits long. [ 5 ] : 299 The general type of instruction is given by the op (operation) field, the highest 6 bits.

In the early 1990s, MIPS began to license their designs to third-party vendors. This proved fairly successful due to the simplicity of the core, which allowed it to have many uses that would have formerly used much less able complex instruction set computer (CISC) designs of similar gate count and price; the two are strongly related: the price of a CPU is generally related to the number of ...
The term is commonly used in association with a metric prefix (k, M, G, T, P, or E) to form kilo instructions per second (kIPS), mega instructions per second (MIPS), giga instructions per second (GIPS) and so on.
This data hazard can be detected quite easily when the program's machine code is written by the compiler. The Stanford MIPS machine relied on the compiler to add the NOP instructions in this case, rather than having the circuitry to detect and (more taxingly) stall the first two pipeline stages. Hence the name MIPS: Microprocessor without ...
