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 ...
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

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 .
During the execute stage, the operands to these operations were fed to the multi-cycle multiply/divide unit. The rest of the pipeline was free to continue execution while the multiply/divide unit did its work. To avoid complicating the writeback stage and issue logic, multicycle instruction wrote their results to a separate set of registers.
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).
[3] Both instructions are more efficient variants of the existing ADC instruction, with the difference that each of the two new instructions affects only one flag, where ADC as a signed addition may set both overflow and carry flags, and as an old-style x86 instruction also reset the rest of the CPU flags. Having two versions affecting ...
MIPS-X, while designed by the same team and architecturally very similar, is instruction-set incompatible with the mainline MIPS architecture R-series processors. The MIPS-X processor introduced the concept of a delayed branch, which includes two delay slots. [1] An MIPS-X processor also includes a Processor Status Word (PSW) register.
