The instruction set consists of 150 different operations. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word ofmemory.a. How many bits are needed for the opcode?b. How many bits are left for the address part of the instruction?c. What is the maximum allowable size for memory?d. What is the largest unsigned binary number that can be accommodated in one word of memory?How many memory accesses does the CPU need to perform during the instruction cycle while executing this instruction?
- A computer has a 256K word addressable memory Module with 16 bits per word. The instruction set consists of 166 different instructions. All instructions have an operation code part (opcode) and an address part (allowing for only one address). Each instruction is stored in one word of memory. Based on the above, answer the following questions: a. How many bits are there in the main memory? (Represent it in power of 2) b. How many bits are needed for the opcode? c. How many bits are left for the address part of the instruction? d. How many additional instructions can be added to the existing 166 without affecting the assigned size of the opcode part? Justify.How many visits to memory does the CPU have to make throughout the instruction cycle while executing this instruction? 2b.DO YOU BELIEVE IT IS TRUE OR FALSE?The benefit of zero-address instruction computers is that their programs are short; the downside is that the instructions need a significant number of bits, resulting in extensive programs.
- Suppose the main memory is completely filled with an equal number of unary and nonunary instructions. How many total instructions would it contain?DO YOU THINK IT'S TRUE OR FALSE?The advantage of zero-address instruction computers is that their programs are short; the disadvantage is that the instructions need a large number of bits, resulting in programs that are quite long.A digital computer has a memory unit with 24 bits per word.
