Define the DMA controller interface.
A DMA controller interfaces along with a few peripherals which may request DMA. The controller chooses the priority of simultaneous DMA requests communicates along with the peripheral and the CPU, and gives memory addresses for data transfer. DMA controller generally used with 8088 is the 8237 programmable device.
The 8237 is actually a special-purpose microprocessor. Normally this appears as part of the system controller chip-sets. The 8237 is a 4-channel device type. All channels are dedicated to an exact peripheral device and able of addressing 64 K bytes section of memory.

Current flow in a circuit
Given an n-channel enhancement MOSFET having V T = 4V, K = 0.15 A/V 2 , I DQ = 0.5A, V DSQ = 10 V, and V DD = 20 V. Using the dc design approach outlined in this section, dete
For zero flag CZ ( Call on Zero ) CNZ ( Call on no zero ) Instructions CZ call the subroutine from the specified memory location if zero flag is set (Z=1). The i
Which clipper would you prefer between the series and the shunt clipper? Why?
Verify the minimum & maximum load current for which the zener diode will keep regulation. Find the minimum value of RL that can be used. The zener diode has V Z = 12V, I ZK =
In the magnetic circuit shown in Figure (a) the coil of 500 turns carries a current of 4 A. The air-gap lengths are g 1 = g 2 = 0.25 cm and g 3 = 0.4 cm. The cross-sectional are
Q. Practical properties of operational amplifiers? To achieve voltage gain and consequently power gain, the op amp must be biased by a dc source. The biasing network is compris
Q. Explain the fixed bias circuit? The Fig refers to the common emitter collector characteristics and the ac and dc load lines.The Fig shows the points Q 1 and Q 2
A 3 phase 400 volt(line to line) wye connected synchronous motor has Xs= 1 ohm per phase and a negligible armature resistance. The field current is so adjusted that the internal(in
LC Filter To the load resistance R L the ripple factor is directly proportional in the inductor filter and inversely proportional to R L in the capacitor filter. Hence i
