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.
Q. Show polarity markings for a single-phase transformer for (a) subtractive polarity, and (b) additive polarity.
With respect to serial communication define the baud rate. The rate of data transfer into serial data communication is denoted in bps. Bits per second (bps) are the rate of in
Q. For a JKFFwith JK = 11, the output changes on every clock pulse. The change will be coincident with the clock pulse trailing edge and the flip-flop is said to toggle, when T = 1
why is delay line used in vertical deflection on systems of CRO?
For a given logic family, consider VOL = 0.25V and VOH = 5 V . For a given circuit, VIL = 0.96 V and VIH = 2.18 V. Find the largest positive-going and largest negative-going nois

The comparison can be made out of two feature 1) Performance and 2) Integrity of Data Write through is better in integrity as it will flush for every writes. Write b
Define the XOR GATE - Microprocessor? The XOR GATE is a alike to an OR gate except for the instance when all the inputs are high. With a XOR gate when all the inputs are high t
what is a mash current theoram
Q. Why FET is called a voltage-controlled device? Why its input resistance is high? In the case of a FET the output current ID is a function of the voltage VGS applied to the i
