A stack organized computer has which of the following instructions?

Consider a processor uses 3-byte instruction format, processor has 1024 register and support 2 – address instruction. If processor support 64 1 – address instruction, then number of 2 – address instruction is _____.

A CPU has 35 registers and uses 12 addressing modes. RAM is 32K × 48. What is the maximum size of the op-code field if the instruction has a register operand and a memory address operand?

Consider an instruction consisting of operation code (opcode), source register and destination identifier along with immediate operand filed. If the 32-bit processor is having 18 registers and instruction set is of size 50. What is the maximum value that an immediate operand can hold if the number system followed by processor is unsigned?

Consider a processor with 28 registers and an instruction set of size 35. Each instruction has four distinct fields, namely, opcode, one source register identifiers, one destination register identifier, and a sixteen-bit immediate value. Each instruction must be stored in memory in a byte-aligned fashion. If a program has 2000 instructions, the amount of memory consumed by the program text is ______ KB. (1 K = 10³)

In 8085 microprocessors, what is the output of following program?

LDA 8000H

MVI B, 30H

ADD B

Assume an instruction set that uses a fixed 20-bit instruction length. Operand specifiers are 6 bits in length. There are K two-operand instructions and no zero-operand instructions. What is the maximum number of one-operand instructions that can be supported?
