a) Give four features that were traditionally reserved to RISC architectures?
b) Determine the overall throughput for 21 sequential instructions assuming a four-stage pipeline and each instruction goes through fetch (7 nanoseconds), decode (2 nanoseconds), execute (1nanosecond) and write-back (10 nanoseconds) stages?
c) Calculate the CPI for a hypothetical 1.8 GHz processor with a benchmarked rating of 500 MIPS?
d) Assume a processor with instruction frequencies and costs as follows
• Integer ALU: 50%, 2 cycles• Load: 25%, 5 cycles• Store: 10%, 3 cycles• Branch: 15%, 2 cycles
Determine which of the following three cases will improve or reduce overall performance and by how much:
CASE 1: Reduce Branch cost to 1 cycle and Store cost to 2 cyclesCASE 2: Reduce Load cost to 3 cycles while increasing ALU cost to 4 cyclesCASE 3: Reduce Load cost to 4 cycles
e) Mention one advantage of using DMA over Interrupt-Driven I/O. Give the basic structure of a basic DMA module.
Unconditional Call Instruction CALL ( Unconditional Call) Instructions :This instruction calls the subroutine program stored at memory location specified in the instruction
The processing speed stated on DATA BUS WIDTH.
Q. The 50-turn coil in the configuration of Figure is rotated at a constant speed of 300 r/min. The axis of rotation is perpendicular to a uniform magnetic flux density of 0.1 T. T
Q. Explain common collector configuration? It is called the common-collector configuration because (ignoring the power supply battery) both the signal source and the load share
Explain the effect of temperature on electrical conductivity of metals. As the temperature is increased, there is a greater thermal motion of atoms which decreases the regulari
Q. Figure gives the frequency-response graphs for a 709 op amp. Choose compensating components for the circuit to have a gain of 100 and a frequency response of up to 100 kHz.
Q. A current i(t) = 20 cos(2π × 60)t A fows through a wire. Find the charge flowing, and the number of electrons per second that are passing some point in the wire.
Explain the programming of 8254 microprocesser. 8254 Programming: All counters are individually programmed through writing a control word, followed with the initial count.
Q. Open-loop control system? An open-loop system is one in which the control action is independent of the output or desired result, whereas a closed-loop (feedback) system is o
