We wish to execute a single LC-3 instruction that will subtract the decimal number 33 from R1 and put the result in R2. Can we do it? a. No, because the smallest number that fits 5 bits is -32b. No, because we don't have SUB instruction to subtractc. No, because the smallest number that fits 5 bits is -16d. Yes, we can do it with a single instruction.e. none of the above.
In some instruction sets, call and return instructions make use of a RR register to hold the return address rather than doing so on the stack. Show how the code in the above problem should be changed if call and return instructions used a RR register for return addresses rather than the stack. Don't change the program's function. 500 MOV R1, X 501 MOV R2, Y 502 MOV R3, Z 503 PUSH R1 504 CALL 550 505 POP R3 506 CALL 560 507 HALT · · 550 PUSH R2 551 CALL 560 552 POP R2 553 RET · · 560 PUSH R3 561 PUSH R1 562 POP R2 563 POP R1 564 RET

Suppose that we are developing a new version of the AMD Barcelona proces- sor with a 4 GHz clock rate. We have added some additional instructions to the instruction set in such a way that the number of instructions has been reduced by 15% from the values shown for each benchmark in Exercise 1.12. The execution times obtained are shown in the following table. a. Name Execution Time (seconds) Reference Time (seconds) bzip2 700 9650 SPECratio 13.7 1.13.2 [10] In general, these CPI values are larger than those obtained in previous exercises for the same benchmarks. This is due mainly to the clock rate used in both cases, 3 GHz and 4 GHz. Determine whether the increase in the CPI is similar to that of the clock rate. If they are dissimilar, why?
LEGv8 does not have a native mov instruction to copy the value in one register to another. The operation can be, however, implemented by utilizing the zero register XZR. For example, copying X1's value to X2 can be achieved using an R-format instruction like op X2, X1, XZR What are the 4 operations that could be used as op in the above instruction to perform the mov operation?
Here, each instruction receives its own data independently of how other instructions get theirs. We utilize: A Multiple Data/Instruction B Multiple Data/Instruction C Singular Data Single Inst D Singe Inst Multiple
In this implementation, each instruction is provided with its own data independently of how other instructions acquire theirs. We insert a(n): A Multiple Input/Output B The Case of Many Pieces of Information or Directions C Unique Information Only One D Several Insts From One
In this case, every instruction receives its own data, independent of how the data for other instructions is obtained. We make advantage of a: A Multiple Data/Instruction B Multiple Iterations of Data or Instruction C Singular Data Single Inst D Singe Inst Multiple
