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.
Current ratio The ratio is mainly used to give an idea of the company's ability to pay back its short-term liabilities with its short-term assets. The higher the current ratio
Q. Show NPN Common Base Amplifier? This configuration is used for high frequency applications because the base separates the input and output, minimizing oscillations at h
Q. Working of Equalizer circuit? Equalizer circuit: Equalizers are combination of passive components (capacitors, resistors and so on) that are used to regulate the amplitude a
Q. When the J and K inputs of a JKFF are tied to logic 1, this device is known as a divide-by-2 counter. Complete the timing diagram shown in Figure for this counter.
Objective: To Understand the Usage of the Output ports of PIC18F452 and make changes in the previous code accordingly. Procedure: 1. Open the p1.asm program from t
Connection of Shunt Capacitors - Vantage Points An unloaded distribution line is capacitive in character and a fully loaded line has inherent inductive and resistive features
Q. Show Crystal - Oscillator Circuits? The simplest crystal-oscillator circuit is shown in Fig. 6-2A. An equivalent circuit is shown in Fig. 6-2B., where C4 represents the grid
explain appropriate first aid procedure to be followed in case of electric shock
what is this?
Q. A wye-connected, three-phase, 50-Hz, six-pole synchronous alternator develops a voltage of 1000 V rms between the lines when the rotor dc field current is 3A. If this alternator
