Hi everyone, I’m Cygnus and I’m interested in the MIPS Malta Qemu (
MIPS Malta BSP Qemu Support (#43) · Issues · RTEMS / Programs / Google Summer of Code · GitLab ) or renode ( #71 ) project. For MIPS experience, I had wrote a MIPS pipeline before (
GitHub - Nambers/0dMIPS: [WIP] in-order 5(+2)-stages pipeline MIPS64r6el SoC implementation with peripheral components, simulated with verilator ).
