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. Use the node-voltage method to find the current I through the 5- resistor of the circuit of Figure.
subranging ADC is a modification
Find the current through each resistor for the networking below using Superposition Theorem.
Q. Can you show Binary Number Formats? We in general write binary numbers as a sequence of bits (bits is short for binary digits) and we have defined boundaries for these bits.
Hexadecimal Number System Similar to octal number hexadecimal number system is also used to represent long binary numbers in smaller form. In microprocessor we use hexad
Q. A satellite radio transmitter has P in = 3 W and G t = 30 dB. The receiving antenna has a circular aperture with radius r at the ground station 30,000 km away. Find r in meter
Explain the NOR GATES - Microprocessor The NOR GATE is an OR gate with the output inverted. Consequently the outputs of a NOR gate would have the opposite states as the outputs o

Q. Explain Power-System Loads? Figure represents a one-line (single-line) diagram of a part of a typical three-phase power system. Notice the symbols that are used for generato
Static V- I Characteristics The static V- I characteristics of power diodes is shown in figure 1.2 when the anode is made positive with respect to cathode the power dio
