QUESTION 4 Consider a microprogrammed system with a control memory of 1024 words of 24 bits. The microinstruction has three fields: (1) microoperations field, (2) select field, and (3) branch address field. The microoperations field has 12 bits. Then the branch address field has (i) bits, and the select field has (ii) bits. (1) 12 O b. (1) 10 (ii) 10 (i) 12 OC (1) 10 Od. (1) 2 (W)2 (4)10 QUESTION 5 Consider an address mapping procedure that provides 8 consecutive microinstructions for each routine. The operation code has 6 bits and the control memory has 2048 words. Given an opcode 011001 in binary (25 in decimal), what is the starting address for its microprogram routine in decimal? O8.200 Ob.100 Oc75 Od. 275
