MIPS and RISC-V are very, very similar. Makes sense if you realize that they modified MIPS and started adding opcode space and features from there. Essentially,

MIPS and RISC-V are very, very similar. Makes sense if you realize that they modified MIPS and started adding opcode space and features from there. Essentially, RISC-V is a modern do-over of MIPS, just with variable length instructions, floating point, and new opcode space and extensions.
