4- The following microinstructions are given RTL code, use Table 7.1 in the Appendix to translate the RTL microinstructions into 20 bit microinstructions. DR MARI, AC AC AC AC+1 AC AC+DR Insert the missing binary code for each of the 20 bit microinstruction given below where DR is initially zero and the starting control memory address is 1000110. F1 F2 F3 BR AD CD 01 01 1000000 Given AC-5531, MIAR]-7634, in hexadecimal, what is the final hexadecimal value of AC when the previous microinstructions are executed in consecutive order b
