29 Facts About MIPS V

The early MIPS V architectures were 32-bit; 64-bit versions were developed later.

In March 2021, MIPS V announced that the development of the MIPS V architecture had ended as the company is making the transition to RISC-V.

MIPS V III was eventually implemented by a number of embedded microprocessors.

MIPS V was completed by the integer-only MDMX extension to provide a complete system for improving the performance of 3D graphics applications.

When MIPS V Technologies was spun-out of Silicon Graphics in 1998, it refocused on the embedded market.

MIPS32 is based on MIPS II with some additional features from MIPS III, MIPS IV, and MIPS V; MIPS64 is based on MIPS V NEC, Toshiba and SiByte each obtained licenses for MIPS64 as soon as it was announced.

MIPS V has joined the RISC-V foundation and future processor designs will be based on the RISC-V architecture.

MIPS V is a modular architecture supporting up to four coprocessors.

MIPS V I has instructions that load and store 8-bit bytes, 16-bit halfwords, and 32-bit words.

Since MIPS V I is a 32-bit architecture, loading quantities fewer than 32 bits requires the datum to be either sign-extended or zero-extended to 32 bits.

MIPS V I requires all memory accesses to be aligned to their natural word boundaries, otherwise an exception is signaled.

MIPS V I has instructions to perform bitwise logical AND, OR, XOR, and NOR.

MIPS V I has instructions to perform left and right logical shifts and right arithmetic shifts.

MIPS V I has instructions for signed and unsigned integer multiplication and division.

MIPS V I has two instructions for software to signal an exception: System Call and Breakpoint.

MIPS V II removed the load delay slot and added several sets of instructions.

MIPS V III is a backwards-compatible extension of MIPS V II that added support for 64-bit memory addressing and integer operations.

MIPS V III added a supervisor privilege level in between the existing kernel and user privilege levels.

MIPS V III removed the Coprocessor 3 support instructions, and reused its opcodes for the new doubleword instructions.

MIPS V IV was designed to mainly improve floating-point performance.

MIPS V IV added several new FP arithmetic instructions for both single- and double-precision FPNs: fused-multiply add or subtract, reciprocal, and reciprocal square-root.

MIPS V added a new data type, the Paired Single, which consisted of two single-precision floating-point numbers stored in the existing 64-bit floating-point registers.

MIPS V has had several calling conventions, especially on the 32-bit platform.

MIPS V EABI is supported by GCC but not LLVM, and neither supports NUBI.

MIPS V processors are used in embedded systems such as residential gateways and routers.
