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.
explain
An audio amplifier with feedback needs gain of approximately 500 in a 3-dB bandwidth extending from 60 Hz to 25 kHz. Assume this is accomplished using a feedback network with ß=0.0
1. Introduction : Theory: The voltage measured across a load follows the Ohm's law which says that the current passing through a conductor between two points is direct
Q Point charges, each of √4πε0 C, are located at the vertices of an equilateral triangle of side a. Determine the electric force on each charge.
Q. Draw the differentiator circuit. Explain its principle of operation with necessary waveforms ? A circuit in which the output voltage is directly proportional to the derivati
Q. Can you show the Decimal to Octal Conversion? To convert decimal to octal is somewhat more difficult. The usual method to convert from decimal to octal is repeated division
Mention how do the NEG & NOT instructions differ in their functionality Here, NOT: The one's complement or logical inversion NEG: The two's complement or arith
Q. For the capacitor shown in Figure connected to a voltage source, sketch i(t) and w(t).
simulate a uniform quantizer that takes as an input a vector of numbers and returns as an output the quantized vector. 1-Generate a random input vector of 10000 samples randomly in
