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.

Active-mode PNP transistors in circuits: In the figure, the arrows showing current point in the direction of conventional current - the flow of electrons is in the opposite di
how started the use of complex variables in circuit analysis for the first time.
The synchronous speed of a wound-rotor induction motor is 900 r/min. Under a blocked-rotor condition, the input power to the motor is 45 kW at 193.6 A. The stator resistance per ph
In continuation of Part-B, the student is required to configure an engine management system for the proposed engine and produce a report including the following: A preamble
When a current is passed through a conductor, a magnetic field is created in its surroundings. We can represent this magnetic field by drawing 'field (or 'flux') lines' with two
Q. A 25-kVA, 2200:220-V, 60-Hz, single-phase transformer has an equivalent series impedance of 3.5 + j4.0 referred to the primary high- voltage side. (a) Determine the highest
Q. What do you mean by Exponent? The exponent field needs to represent both negative and positive exponents. To perform this, a bias is added to the actual exponent in order
