After MIPS was sold for several times, the final outcome was not bad. MIPS went to open source. Last weekend, the official announcement of the MIPS R6 instruction set and related tools, 32-bit, 64-bit MIPS can be downloaded for free.
In 2012, Imagination Technologies spent $100 million to acquire MIPS, which is preparing to strengthen the CPU business, so that it can provide complete CPU and GPU licenses. However, Imagination Technologies is not successful in this regard. After Apple gave up its PowerVR GPU license, Imagination Technologies also sold the MIPS business, and now MIPS is in the hands of Wave Computing.
At the end of last year, Wave officially announced that it will open the MIPS Architecture (ISA) to provide a free MIPS architecture for semiconductor companies, developers and universities worldwide to develop next-generation SOCs. The MIPS Architecture Open Plan will provide all participants with the latest 32-bit and 64-bit MIPS architectures free of charge, without generating architectural license fees and royalties, and providing hundreds of entries worldwide for all MIPS architecture users. Patented protection.
Currently, Wave official website has begun to provide MIPS open source related instruction sets and tools, including 32-bit and 64-bit MIPS R6 instruction set, MIPS SIMD extension, MIPS DSP extension, MIPS Multi-Threading (MT), MIPS MCU, microMIPS Architecture. Architecture, MIPS Virtualization (VZ) virtualization, and more.

In terms of processor instruction set, MIPS still has advantages in some aspects, and the ecosystem has a certain foundation. After open source, its appeal will also be enhanced. For domestic companies, the X86 architecture is not possible, ARM can authorize the purchase, but the initiative is still in the hands of ARM, the open source CPU instruction set has two choices of RISC-V and MIPS, the former gradually in China Rising, many companies have joined the RISC-V camp. MIPS has Junzheng and Loongson companies in China. Loongson is the best development, but their MIPS instruction set is bought out. Changed, I don't know if Longxin will embrace open source MIPS after MIPS is completely open sourced.
