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.
Ratiometer type frequency meter
Can I get some ideas for power system stability simulation using Matlab?
Explain SAHF instructions in 8086 family with example and their effect on flag. SAHF: Store AH register in flag register, this is an instruction utilized to store the data i
Q. What is a clamper? Differentiate between a clamper and clipper. Clamping network shifts (clamps) a signal to a different dc level, i.e. it introduces a dc level to an ac sig
1. In the circuit shown below, the capacitor initially has a voltage across it 4 Volts (at t = 0). a. Write down the expression for V C (t) when the switch is closed. b. Wr
Factors Affecting Choice of Observation: Observers are influenced by a number of factors in the process of observation. Black and champion have identified three such factors.
Define Series VAr Compensation? For very long transmission lines, the inductive reactance of the line becomes so high that not much power can be transmitted through the line, s
Explain the Tap Changing Transformers? This is the most popular form of voltage control at all voltage levels. It is based on changing the turns ratio of the transformer, hence
A 100kw,230v,dc shunt generator,with Ra=0.05,and Rf=57.5 has no load rotational loss(friction,wandage,core loss)of 1.8kw.compute a) The generator efficiency at full load.
A permanent magnet DC motor is being considered for use as a drive motor for a vehicle. The motor is known to have the following properties No load speed @ 100 V = 2000 rpm torq
