I'm trying to pick the highest of 4 values using the SRT instruction. The attached ladder works but seems somewhat cludgy. The done bit toggles every scan and initiates a sort. The sort array switches between the original values and the sorted values. (back and forth) I'd rather use the SRT instruction than other code since the number of values may rise substantially. The question - is this the correct useage of SRT?
