- In a dual core processor, consider first four letters of your name coming as processes each having size equal to its ASCII code in MBs. Size of memory is 250 MB. Write down the sequence of using ready queue, wait queue. If a vowel comes in these letters, an interrupt of I/O will be generated Note: My Name is Razzaq .Registers in RISC-V are 64-bit. For the sake of simplicity, consider the following instructions operating on 32-bit registers. Assume that registers x5 and x6 hold the values 0xBBBBBBBB and 0x00000000, respectively. What is the value in x6 for the followingslli x6, x5, 6 Using the result from the part above, what is the value in x6 for the following instruction. srli x6, x6, 6Task Write a program in the ARMLite assembly language which generates the Fibonacci number F(12) and stores the value in register R6. • You must use a loop to generate the value. Partial marks will be given for otherwise correct but non-loop based solutions • There is no limit on the number of registers you can use • The stack memory may be used, but is not required • Other memory access is not allowed or needed • Add a comment to the top of your program describing it's behaviour. You should make use of comments to describe your code's sections. Submit your program as a plain text file. If you are using the ARMLite simulator, it can be exported directly using the 'Save' button.
- In x86-64 assembly, how many registers do we have, and can we use registers like %rsp for anything we like? Group of answer choices A. We get 8664 general-purpose registers. Registers are like variables in assembly where we can store information. We can in theory use them for whatever we want, however we do need to follow conventions in order for our program to operate without errors (%rsp for example keeps track of the stack pointer). B. We get unlimited general-purpose registers. Registers are like variables in assembly where we can store information. We can use them for whatever we want. C. We get 16 general-purpose registers. Registers are like variables in assembly where we can store information. We can in theory use them for whatever we want, however we do need to follow conventions in order for our program to operate without errors (%rsp for example keeps track of the stack pointer).Write a program in HACK assembly, without using symbols, that computes thebitwise exclusive or (XOR) of the values stored in RAM[1] and the value of thememory location with address stored in RAM[2]. The result of the computationshould be stored in RAM[0].You can think of RAM[2] as being a pointer to where the second operand of the XORis stored.When QS1 = 0 and QS0 = 1, then which of the following is true, O a. Subsequent byte is fetched from instruction queue O b. No operation O. queue is emptied O d. first byte of opcode is fetched from instruction queue
- For this assignment, you are to write a MIPS assembly language program using the MARS IDE and assume a system has 31-bit virtual memory address (so no worry about negative numbers) with a 4-KB page size (4096 bytes). Write a MIPS program that accepts an integer input that represents a virtual address and outputs the page number and offset for the given address in decimal. The output should look like: The address 19986 is in: Page number = 4 Offset = 3602 Check to make certain your program works. You can use the output from 19986 given above as a test, but I will use other numbers to test it. Submit the MIPS assembly language code and a screenshot showing a test run.In this problem we want to modify the single cycle datapath shown below (also in in slide #1 of "chapter3_single_cycle_datapaths.pptx") so that it supports execution of a new instruction called jump register (jr). PC Add Read address Instruction [31:0) Instruction [25:21) Instruction [20:16] Instruction Instruction [15:11] memory (DMUXT RegDst Instruction [15:0] RegWrite Read register 1 Read register 2 Read data 1 Write Read register data 2 Write data Registers 16 Sign- extend Instruction [5:0] 32 Shift left 2/ ALUSrc (OMUXI) ALU Addresult Zero ALU ALU result ALU control ALUOP #copy contents of "rs" register to PC (PC = $rs) PCSrc ( E3X MemWrite Read data Address Data Write memory data MemRead MemtoReg (-MUXO) jr $rs You are allowed to add new control signal(s), wire(s), muxe(s) to support this instruction. First briefly explain the required modifications. Then indicate the value of each control signal (RegDst, RegWrite, ALUSrc, ALUOP, MemRead, Mem Write, MemToReg). You must use "X"…When translating conditionals or loops, the generated low-level code contains jumps. For the CPU to be able to execute a jump, the target of a jump must be a valid memory address. However, code generators typically generate jumps to symbolic addresses (labels). For example: beq exit Answer the following questions about symbolic addresses. i. What are the advantages of using symbolic addresses? ii. Which programs are responsible for translating such symbolic addresses to actual memory addresses? iii. How do code generators create symbolic addresses?
- Consider a hypothetical computer having instruction length 32 bit and Byte addressable memory. You need to run a program P having 10 Q.4 CO4 instructions 11,12,13...10. All the instructions are stored in consecutive memory locations started from 1000. To run an instruction li, you have to complete four operations: Fetch, Decode, Execute, and Store. The content of Program Counter will be after the completion of fetch operation of instruction 12. There are no jump or branch instruction in program Phe pipeline is a way to improve the performance of the processor by increasing thethroughput. As you learned in the class, the instruction execution is divided to 5stages: IF, ID, EX, WB, and MEM. At each stage the processor can pipeline morethan one instruction so that they execute at the same cycle. Recall that some stagecannot be overlapped. For instance, you cannot issue to memory reads at the samestage.Write a program using your favorite programming language that reads assembly codelike the following:LW $0, $1(20) –load instruction at address $1 + 20 and put the result in register $0.ADD $3, $0, $2 –add the content of register $0 to register $2 and store the outcome inregister $3.Your program must simulate the pipeline by creating an execution schedule. Theprogram must determine the dependencies between the instructions, if any, and stallthe pipeline as necessary. The program must show the execution table including thestalls if any. Finally, the program must also output the number…In an RISC V (32-bit) microprocessor, if a0 is preloaded with data of Ox0000_1F75 and al is preloaded with data of Ox0000_32CB, then what are the values of s0 (in Hex) after each of the following logical operations (in sequence)? xor s0, a0, al xori s0, s0, 0XFFFF slli s0, s0, 16
