These instructions are needed for the MVP. We need MULHU for immediate division and NE for the logical operators (and, or, not). Following the format of our ISA, the spec for these instructions are:

NE:
Operands: a, b(fp), c(fp)
Description: If [b] != [c] then set a to 1. Otherwise, set a to 0.

MULHU:
Operands: a, b(fp), c(fp)
Description: Multiply [b] by [c] then set a to the top part of the result.

Also MULHS and SRA for SDIV.
