a. Describe the memory allocation schemes in an embedded system. Also give a short-note on extended memory. (6)
b. Consider a byte - addressable computer with 16 - bit addresses a cache capable of storing a total of 4 K bytes of data and blocks of 16 bytes. Show the format (containing field names and sizes) of memory address for:
(i) Direct mapped (ii) Fully associative
(iii) 4 - way set associative
Q. A balanced wye-connected load with a per-phase impedance of 4 + j 3 is supplied by a 173-V, 60-Hz three-phase source. (a) Find the line current, the power factor, the tota
Define super scalar architecture. Super scalar architecture: The Pentium microprocessor is organized along with three execution units. Individual executes floating-point inst
Q For a parallel-plate capacitor with plates of area A m 2 and separation d m in air, the capacitance in farads may be computed from the approximate relation Compute the a
Q. Show Power and Power Factor in ac Circuits? Power is the rate of change of energy with respect to time. The unit of power is a watt (W), which is a joule per second (J/s). T
Q. Why is an emitter bypass capacitor used in an RC coupled amplifier? If an emitter resistor Re is used for self-bias in an amplifier and if it is desired to avoid the degene
Limitations: 1. Silicon transistors do not function at voltages much higher than about 1,000 volts (SiC devices can be worked as high as 3,000 volts). In difference, electron
An industrial plant consumes 500 kWat a lagging power factor of 0.6. (a) Find the required kVA rating of a synchronous capacitor to improve the power factor to 0.9. (b) If a
Thyristor The name thyristor is derived bya combination of the capital letters from thyratron and translstor. This means that thyristor is a solid state device like a
