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.
The R8000 issues at most one integer store per cycle, and one final read port delivers the integer store data. Two register file write ports are used to write results from the two integer functional units. The R8000 issues two integer loads per cycle, and the other two write ports are used to write the results of integer loads to the register file.
The MIPS III defines two register files, one for the integer unit and the other for floating-point. Each register file is 64 bits wide and contained 32 entries. The integer register file has two read ports and one write port, while the floating-point register file has two read ports and two write ports.
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.
The R4600 was a simple design; it was a scalar processor, issuing up to one instruction per cycle to its integer pipeline or floating-point unit (FPU). Most integer instructions have a single cycle latency and throughput, except for multiplies and divides. Multiplies, 32-bit and 64-bit, have an eight-cycle latency and six-cycle throughput.
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 R4200 is a microprocessor designed by MIPS Technologies, Inc. (MTI) that implemented the MIPS III instruction set architecture (ISA). It was also known as the VRX during development. The microprocessor was licensed to NEC, and the company fabricated and marketed it as the VR4200. The first VR4200, an 80 MHz part, was introduced in 1993. A ...
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
