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 intervals
2. Draw an R-type datapath with an Instruction Fetch unit. Point to be noted, the ISA and ALU both are 16-bits. R-type Op (4 bit) Rs (4 bit) Rt (4 bit) Rd (4 bit)
Question 24 Consider instruction in which the instruction does nothing. It just occupies space. Choose the correct sequence of circuits which will correctly implement this instruction. TMP below is a temporary register. NOP IP->MAR MEM(MAR)-> MDR MDR->IR TMP->AX AX->TMP IP-> ADDR(IR) IP->MAR MEM(MAR)-> MDR MDR->IR AX->BX BX->AX IP -> ADDR(IR) IP->MAR MEM(MAR)-> MDR MDR->IR IP -> ADDR(IR) IP->MAR MEM(MAR)-> MDR MDR->IR IP -> IP+2
2. Consider the following instruction: beq $t0, $t1, 0xA010 What are the values of Control signals generated by the MIPS architecture to execute this instruction. Show with a chart and explain it all clearly. (You may draw a simplified datapath flow)
The following sequence of instructions will execute on the 5-stage pipelined MIPS datapath: I-MEM Address Instruction OXAO L1: slt $t4, $t0, $t1 OXA4 beq $t4, $1, L2 OXA8 slt $14, $t0, $t2 OXAC beq $t4, $1, L2 OXBO slt $t4, $t0, $t3 ОхВ4 beq $t4, $1, L2 OXB8 j L3 OXBC L2: addi $t0, $t0, 5 OXCO j L1 ОХC4 L3: List data dependencies for the entire code (i.e. a->b would mean instruction b is dependent on instruction a ): Which data dependencies are hazards? How many clock cycles does it take to execute the entire code for a normal pipelined processor? (i.e. all 5 stages of the last instruction have been completed) How many clock cycles will it take for a 2-issue in-order superscalar pipelined processor to execute the entire code?
For example, suppose an instruction is not accepted and VA page 30 is generated. A software-managed TLB can outperform a hardware-managed TLB in the following cases:
There is the potential for independent operations to be carried out on the data bus, the address bus, and the control bus?
Datapath for the LDI Instruction 7 Recently we have been discussing the importance of the datapath and its relationship to the Register Transfer Notation and control signals need to execute instructions in the datapath. Answer the following questions about this specific What is the ML (or binary instruction) of this single instruction? Give your answer in hexadecimal. instruction: type your answer... LDI R4, data Where the label data is at address x3005, and the LDR instruction is at address x3000. What is the Register Transfer notation for this instruction? Remember to change the destination and source registers to the actual registers of the instruction. type your answer... List in order all the controls signals required to execute this instruction. You do not need to list the signals for fetching and decoding the instruction.
