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 ...
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 ...
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
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.
Increasing the number of registers in an architecture decreases register pressure but increases the cost. [12] While embedded instruction sets such as Thumb suffer from extremely high register pressure because they have small register sets, general-purpose RISC ISAs like MIPS and Alpha enjoy low register pressure. CISC ISAs like x86-64 offer ...
But the programmer, especially if programming in a language supporting large integers (e.g. Lisp or Scheme), may not want wrapping arithmetic. Some architectures (e.g. MIPS), define special addition operations that branch to special locations on overflow, rather than wrapping the result.
The MIPS ISA was based on a 32-bit word. It supported 32-bit addressing, and was word-addressed. It was a load/store architecture—all references to memory used load and store instructions that copied data between the main memory and 32 general-purpose registers (GPRs). All other instructions, such as integer arithmetic, operated on the GPRs.
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
