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.
Q. The energy stored in a 2-µF capacitor is given by w c (t) = 9e -2t µJ for t ≥ 0. Find the capacitor voltage and current at t = 1s.
For the motor speci?ed in figure, compute the following: (a) The load component I' 2 of the stator current, the internal torque T, and the internal power P m for a slip of 0.
Questions: A magnetic core with a primary winding with 40 turns and a secondary winding with 80 turns has a leakage path dominated by an air gap as shown in the figure. The iro

Q. Determine the time delay of the cable? An RG-213/U (radio guide 213/universal coaxial cable) is a small-sized, flexible, double-braided cable with silvered-copper conductors
explain how conduction take place in conductor
y more number of resistance and capacitor are used in a circuit what is the purpose to add ore than one..?
Explain Contact resistance. Contact resistance: It is measured as the voltage drop from tail to tail of the mated contacts along with specified current flowing through the cont
