Write control sequences for the swap instruction implemented in 1-bus microarchitecture.      swap(:= op = 7) (R[ra] R[rb]: R[rb] R[ra])

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

For example, suppose an instruction is not accepted and VA page 30 is generated. For the following use cases, a TLB controlled by software might be preferable than one handled by hardware:

An 'instruction fetch/read' results in three sets of numbers that go to the Registers Block as studied in class. These three numbers in the instruction represent bits 25-21 for 'Read Register 1', bits 20-16 for 'Read Register 2', and bits 15-11 for the 'Write Register'. What does the 5 bits width of each of these indicate? a. That the word is 15 bits long in this architecture b. That each word is 32 bits long c. That there are 32 registers that can be addressed in this architecture d. That there are 15 registers that can be addressed in this architecture

Draw a diagram showing the relationship of the EDX, DX, DL and DH registers. Page 29 shows EAX that you can follow as a template. Template attached

Question 2 Let's assume %rcx = 1F5 and %rax= C3F (Hexadecimal representation). What is the value in %rcx after the following instruction: OR %rax, %rcx Provide answer in hexadecimal representation. Acceptable answer format: 3FD or 3fd or (3fd)16 or (3FD)16 Question 4 Let's assume %rsi = (2DE) 16 and %rdx= (FC2) 16 (Hexadecimal representation). What is the value in %rdx after the following instruction: AND %rsi, %rdx Provide answer in hexadecimal representation. Acceptable answer format: 3FD or 3fd or (3fd)16 or (3FD)16 Question 5 What is the two's complement of (11000000)2? Question 5 options: Question 6 What is the decimal value of the signed integer (11110100) 2?
