As I understand it a constant is added to the contents of rs. The the
content of rt is replaced by this sum. Is that correct??

Yes, a 16-bit signed immediate is added to the value of Rs and then put into
Rt.

In typical RISC architectures only load and store instructions access memory,
and everything else operates just on registers.
