the value of $1 in the decoding phase, at this time, 1st Ori commands are still in the execution phase. Therefore, the result is not calculated by the 1st Ori commands. If you calculate this value, errors will inevitably occur. 5-1. This situation can be called data correlation between adjacent commands. For openmips, it can also be called data correlation in th
