Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer.

Suppose R1 contains 0005 and R2 contains Odc1, and the address of x is 00d1. What is the effective address in this instruction? lea R2,6(R1) tive the answer as a single hex word, with no S Example format of answer: F32b (four consecutive hex digits) Answer:
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
What is the main difference between the MUL instruction's multiplication product and the IMUL instruction, which only needs a single operand?
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.
What is the main difference between the JMP instruction and the JSRR instruction? There is no difference, JMP is a pseudo instruction for JSRR The JMP does not back up the PC into R7 and the JSRR instruction does JSRR uses the PC to calculate the effective address, and JMP uses a base register The JSRR does not back up the PC into R7 and the JMP instruction does JMP uses the PC to calculate the effective address, and JSRR uses a base register
