A digital computer has a memory unit with 24 bits per word. 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 of memory.1. a) How many bits are needed for the opcode?2. b) How many bits are left for the address part of the instruction?3. ◆c) What is the maximum allowable size for memory?4. d) What is the largest unsigned binary number that can be accommodated in one word of memory?
A computer with a 32-bit word uses an instruction format that includes direct and indirect addressing of 8 megabytes and one of 16 registers. The highest order bits are used for the opcode, followed by the bits indicating the register, followed by the indirect/direct bit, followed by the bits indicating the memory address. Draw the instruction word's format, showing how many bits are used for all four fields (Make sure to show here how many bits for each and the order in which they appear. You can submit a drawing of the word's format separately

Assume a CPU with a fixed 32-bit instruction length has the following instruction format:opcode mode [operand1] [operand2] [operand3]The mode encodes the number of operands and each operand’s mode. For instance, one mode indicates three registers, another indicates two registers and an immediate datum, another indicates a main memory reference, etc. Assume there are 94 instructions and 22 modes. Answer the following.a. One mode indicates three registers. How many registers can be referenced in this mode?b. One mode indicates two registers and an immediate datum in two’s complement. Assuming there are 32 registers, what is the largest immediate datum that can be referenced?c. One mode has a destination register and a source memory address (an unsignednumber). Assuming 16 registers, what is the largest memory reference available?d. One mode has two memory addresses, both using base displacement. In both, the basesare stored in index registers and the displacements are specified in the…
