Architecture of 8085 Microprocessor
The 8085 microprocessor is an 8 bit general purpose microprocessor. 8 bit processor means it can read write and process 8 bit data at a time. The 8085 microprocessor chip has 40 pins requires +5 V power supply and can operate with a 3MHz clock frequency.
Although the internal architecture of 8085 microprocessor is very complicated the programme is concern only with a small part of it which can be referred in the program or which is important to know to the write a program. The block diagram showing this part is called the programming model of the microprocessor. To understand the basic and important functions of 8085 microprocessor we will concentrate only on the programming model here. The detail architecture of 8085 microprocessor will be discussed later.
Modern complex systems are normally constructed by interconnecting sub-units. Therefore the systems engineer is often not too concerned about the details of what is inside these
Conceive a system composed of a very large number N of distinguishable atoms at rest and mutually noninteracting, each of which has only two (nondegenerate) energy levels:0,ε>0 Let
Explain priority interrupts of 8085. The 8085 microprocessor has five interrupt inputs. They are TRAP, RST .5, RST 6.5, RST 5.5, and INTR. These interrupts have a fixed prio
Program Description In the above program any two numbers can be stored in register A and B ( by replacing XX and YY). Contents of B are compared with A. If B CY = 0
A rifle with a mass of 3,5 kg fires a bullei with a mass of 120 g with a muzzle velocity of 420 mls. Calculate the following: 1.4.''l The momentum before the rifle was fired ''1.4.
UJT as relaxation oscillator: The UJT relaxation oscillator is shown in fig. it consist of a UJT and a capacitor C which is charged through a variable resistance R when VBB is
Q. The external - characteristics data of two shunt generators in parallel are given as follows: Load Current, A: 0 5 10 15 20 25 30 Terminal voltage I, V: 270 263 254 240 22
Q. Determine the bits required for a D/A converter to detect 1-V change when V ref = 15 V.
Q. Explain Read-only memory? ROM is nonvolatile (because it maintains its contents even when its power is shut off) and is used to store data and programs that do not change du
