MIPS is a modular architecture supporting up to four coprocessors (CP0/1/2/3). In MIPS terminology, CP0 is the System Control Coprocessor (an essential part of the processor that is implementation-defined in MIPS I–V), CP1 is an optional floating-point unit (FPU) and CP2/3 are optional implementation-defined coprocessors (MIPS III removed CP3 ...
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 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 terms multi-core and dual-core most commonly refer to some sort of central processing unit (CPU), but are sometimes also applied to digital signal processors (DSP) and system on a chip (SoC).
All MIPS, SPARC, and DLX instructions have at most two register inputs. During the decode stage, the indexes of these two registers are identified within the instruction, and the indexes are presented to the register memory, as the address. Thus the two registers named are read from the register file. In the MIPS design, the register file had ...
The FMA instruction set is an extension to the 128 and 256-bit Streaming SIMD Extensions instructions in the x86 microprocessor instruction set to perform fused multiply–add (FMA) operations. [1]
A CPU (a MIPS CPU) A hard drive; An interrupt controller, timer, and misc. other components; which are there to run the Nachos [1] user space applications. That means that you can write programs for Nachos, compile them with a real compiler (an old gcc compiler [2] that produces code for MIPS) and run them.
