Wave computing turns mips architecture into open source

Wave Computing's MIPS instruction set architecture has been a huge part of consumer computing throughout the years, being extremely popular in the 1990s and 2000s due to its use on consoles as well as supercomputers of the time.

MIPS architecture becomes Open Source

The golden age of MIPS is behind the arrival of the open source RISC-V architecture, something that has finally led Wave Computing to release the MIPS code, eliminating license fees and royalties for its use, in addition to offering it to all through MIPS Open. Wave Computing hopes this move will accelerate the ability of semiconductor companies, developers, and universities to adopt and innovate using the MIPS architecture as the basis for next-generation system-on-chip designs.

Full details on MIPS Open are expected to be revealed in the first quarter of 2019, revealing exactly how free and open it will become, though this move will undoubtedly increase MIPS popularity among chipmakers. The MIPS Open program will allow participants to download the basic IP, support mechanisms, and licenses for hundreds of architecture patents, although at this time it is unknown how the approach will compare to the open source nature of RISC-V.

MIPS is a modular architecture that supports up to four coprocessors. In MIPS terminology, CP0 is the system control coprocessor, an essential part of the processor that is defined by the implementation in MIPS I-V, CP1 is an optional floating point unit (FPU), and CP2 / 3 are coprocessors Implementation-defined options. For example, on the PlayStation video game console, CP2 is the Geometry Transformation Engine (GTE), which speeds up the processing of geometry in 3D computer graphics.
