Given the sequence of 16-bit control words below for the datapath in Figure and the initial ASCII character codes in 8-bit registers, simulate the datapath to determine the alphanumeric characters in the registers after the execution of the sequence. The result is a scrambled word: what is it?
011 011 001 0 0010 0 1 | R0 | 00000000 |
100 100 001 0 1001 0 1 | R1 | 00100000 |
