Introducing a nanoMIPS port for Linux

2018-05-02 Thread James Hogan
Yesterday MIPS Tech announced the latest generation of the MIPS family of architectures called nanoMIPS [1]. As part of the development we have been designing all the open source tools necessary to support the architecture and, thanks to the speed with which we were able to prototype, we have also
