- How does pipelining improve CPU efficiency? What’s the potential effect on pipelining’s efficiency when executing a conditional BRANCH instruction? What techniques can be used to make pipelining more efficient when executing conditional BRANCH instructions?If a microprocessor has a cycle time of 0.5 nanoseconds, what’s the processor clock rate? If the fetch cycle is 40% of the processor cycle time, what memory access speed is required to implement load operations with zero wait states and load operations with two wait states?Add control states to the following to implement an exchange-with-memory instruction, xchg. such that xchg $rt,immed($rs) acts rather like the combination of a MIPS lw and sw: the result should be as if a sequence like t=memory[immed+rs]; memory[immed+rs]=rt; rt=t; where t is a temporary register. In case you were wondering why one would ever want to do this, it's actually a very common operation for synchronizing between concurrently executing processes using sempahores... but MIPS doesn't happen to do it this way, so it's also not a MIPS instruction. You're probably wondering where the t register is. Well, pick one you're not using... perhaps y (although you have to be careful about when you compute immed+rs for that to work). You should use the encoding suggested by the when below, so an instruction like xchg $9,4($10) would be encoded as op(3)+rt(9)+rs(10)+immed(4). when (op()) (op(3)) XchgStart: PCout, MARin, MEMread, Yin CONST(4), ALUadd, Zin, UNTILmfc MDRout, IRin Zout, PCin,…

Select one or more A. The binary loader overcomes the problem by positioning instructions at word boundaries so that PC can be calculated. B . PC is incremented by the largest possible foxed value, irrespective of the variability of the instruction C. Increment value is known when the current instruction has completed execution.

- Orthogonality refers to the presence of a "backup" instruction in an instruction set design that may be used in place of any other instruction that achieves the same aim. The onus is on you to confirm or refute my assumption.Please write down the microinstructions to implement the instruction MOV R0, [R1], moving the contents of the memory cell pointed by R1 tothe register R0. Please add a short but significant explanation to each single microinstruction. olve this question in great detail explaining every single bit of info as i'm a complete beginner and i need to understand how to solve questions of this type. also provide small examples of how the solution would differ if the question was slightly altered. THANK YOU!Please don't copy Explain what happens when the POP CX instruction executes. Make sure to show the physical addresses where data are stored. (Assume that SP = FFFEH and SS = 1000H before execution.)
- 19. The 8085 microprocessor respond to the presence of an interrupt a. As soon as the trap pin becomes ‘LOW’ b. By checking the trap pin for ‘high’ status at the end of each instruction fetch c. By checking the trap pin for ‘high’ status at the end of execution of each instruction d. By checking the trap pin for ‘high’ status at regular intervalsConsider a HW ISA program P1 with the following Instruction Memory IM: a. fill in the execution table for program P1 using the IM. Use the same notational conventions used in the example execution table for P0 below. Any numbers beginning with 0x will be interpreted as hexidecimal; any numbers not beginning with 0x will be interpreted as decimal. b. Show the final values of the registers R2, R3, and R4 when the program execution halts. Again, any numbers beginning with 0x will be interpreted as hexidecimal; any numbers not beginning with 0x will be interpreted as decimal.Orthogonality is the ability of an instruction set architecture to have a "backup" instruction for any instruction that does the same task. Tell me whether that's correct or not.
