MIPS I has thirty-two 32-bit general-purpose registers (GPR). Register $0 is hardwired to zero and writes to it are discarded. Register $31 is the link register. For integer multiplication and division instructions, which run asynchronously from other instructions, a pair of 32-bit registers, HI and LO, are provided. There is a small set of ...
The R2000 is a 32-bit microprocessor chip set developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture (ISA). Introduced in January 1986, it was, by a few months, the first commercial implementation of the RISC architecture.
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 ...
It is a versatile processor designed for mobile devices and other low power electronics. This processor architecture is capable of up to 130 MIPS on a typical 0.13 μm process. The ARM7TDMI processor core implements ARM architecture v4T. The processor supports both 32-bit and 16-bit instructions via the ARM and Thumb instruction sets.
The R3000 is a 32-bit RISC microprocessor chipset developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture (ISA). Introduced in June 1988, it was the second MIPS implementation, succeeding the R2000 as the flagship MIPS microprocessor. It operated at 20, 25 and 33.33 MHz.
It has a 16- or 32-byte line size. Architecturally, it could be expanded to 32 KB. During the third stage (RF), the instruction is decoded and the register file is read. 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 first group specifies the destination GPR, and the second specifies the source GPR. The last sixteen bits specify the immediate value, that is, the 16-bit signed (two's compliment) integer that is added to the second register and then stored in the first register. The equivalent mnemonic in MIPS32 assembly is also shown.
