Question 20 5 pts Suppose a computer has 32-bit instructions. The instruction set consists of 64 different operations. All instructions have an opcode and two address fields (allowing for two addresses). The first of these addresses must be a register direct address, and the second must be a memory address. Expanding opcodes are not used. The machine has 16 registers. What's the size of the largest memory space that can be addressed by this computer?Assume byte addressable memory.

(d) 7650 (e) None of the above Question 7 [18 Points]-Instruction Set Architecture (ISA) I. Suppose an instruction set has 32-bit instructions. Every instruction has an 8-bit opcode and a 12- bit immediate operand. Some instructions have three register operands (two sources and a destination register). Every instruction that uses registers must be able to specify any of the registers. How many registers can this instruction set support? (a) 32. (b) 64. (c) 16. (d) There is not enough information...

A digital computer has a memory unit with 24 bits per word. The instruction set consists of 199 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 of memory. [] How many bits are needed for the opcode? How many bits are left for the address part of the instruction? What is the maximum allowable size for memory? What is the largest signed...

Consider a hypothetical computer with an instruction set of only two n-but instructions. The first bit specifies the opcode, and the remaining bits specify one of the 2-1 n-bit words of main memory. The two instructions are as follows: SUBS X: Subtract the contents of location X from the accumulator, and store the result in location X and the accumulator JUMP X: Place address X in Program Counter A word in memory may contain either an instruction or a binary...
