Hi,
In 2017 Exan Moed B we were asked to write the new value of various registers after executing the instruction “sw R2 R3 12” which is I-Type instruction.
If I get it right, in terms of the control path, this instruction goes through D5 to COPYGPR2MDR mode in which MDR gets the value that is stored in register B.
I don’t understand how B is related to this I-type instruction. B is suppose to contain RS2 which isn’t encoded in I-type instruction, isn’t it?
If anyone could help me with this I’ll be glad,
Thanks!
