'Which of the following is NOT true of machine instruction code? It has an instruction format: Its bit pattern is for specific machines. It hos clear addressing formats: All machines have same instructions format;'
Sanchit J.
Answer the following questions in terms of the machine language described in Appendix C. a. Write the instruction 2304 (hexadecimal) as a string of 16 bits. b. Write the op-code of the instruction B2A5 (hexadecimal) as a string of 4 bits. c. Write the operand field of the instruction B2A5 (hexadecimal) as a string of 12 bits.
The memory unit of a computer has $256 \mathrm{k}$ words of 32 -bits each. The computer has an instruction format with four fields: 1. An operation field 2. A mode field to specify one of 8 addressing modes 3. A Register address field to specify one of 120 processor registers. 4. A memory address. Then what is the number of bits in each field respectively if the instruction is in one memory word? (A) $4,3,7,18$ (B) $3,4,7,18$ (C) $2,1,6,23$ (D) $3,7,4,18$
