Which of the following is true while executing data transfer instructi...
Answer:

The correct option is (C) - both operands can be direct/indirect register operands.

When executing data transfer instructions, there are several important considerations to keep in mind.

1. Program Counter Access:
- The program counter (PC) is a register that keeps track of the memory address of the next instruction to be executed.
- While executing data transfer instructions, the program counter is accessible and can be modified if necessary. Therefore, option (a) - "program counter is not accessible" is incorrect.

2. Restricted Bit-Transfer Operations:
- Bit-transfer operations involve transferring bits from one location to another.
- While executing data transfer instructions, there are no restrictions on bit-transfer operations. Therefore, option (b) - "restricted bit-transfer operations are allowed" is incorrect.

3. Operand Types:
- Data transfer instructions involve transferring data from one location to another.
- These instructions typically involve two operands - the source operand and the destination operand.
- Both operands can be direct register operands, meaning they directly reference a register in the CPU.
- Additionally, both operands can be indirect register operands, meaning they reference a memory location that contains the address of the actual data.
- Therefore, option (c) - "both operands can be direct/indirect register operands" is correct.
- This flexibility allows for efficient data transfer between registers and memory locations.

In conclusion, while executing data transfer instructions, the program counter is accessible, there are no restrictions on bit-transfer operations, and both operands can be direct or indirect register operands. Therefore, option (c) is the correct choice.

Similar Computer Science Engineering (CSE) Doubts

An instruction pipeline has five stages where each stage take 2 nanoseconds and all instruction use all five stages. Branch instructions are not overlapped. i.e., the instruction after the branch is not fetched till the branch instruction is completed. Under ideal conditions,a. Calculate the average instruction execution time assuming that 20% of all instructions executed are branch instruction. Ignore the fact that some branch instructions may be conditional.b. If a branch instruction is a conditional branch instruction, the branch need not be taken. If the branch is not taken, the following instructions can be overlapped. When 80% of all branch instructions are conditional branch instructions, and 50% of the conditional branch instructions are such that the branch is taken, calculate the average instruction execution time. Correct answer is 'Each stage is 2 ns.'. Can you explain this answer?

A processor X1 operating at 2 GHz has a standard 5-stage RISC instruction pipeline having a base CPI (cycles per instruction) of one without any pipeline hazards. For a given program P that has 30% branch instructions, control hazards incur 2 cycles stall for every branch. A new version of the processor X2 operating at same clock frequency has an additional branch predictor unit (BPU) that completely eliminates stalls for correctly predicted branches. There is neither any savings nor any additional stalls for wrong predictions. There are no structural hazards and data hazards for X1 and X2. If the BPU has a prediction accuracy of 80%, the speed up (rounded off to two decimal places) obtained by X2 over X1 in executing P is ______. Correct answer is between '1.42,1.43'. Can you explain this answer?
