The total memory location required to feed the instruction in memory is called as instruction word size. The memory location of 8085 microprocessor can accommodate 8-bits of data. To store 16-bits data, they are stored in two consecutive memory locations (i.e. 2 Bytes). According to the instruction word size in 8085 microprocessor, there are three types of … Read more
In this article, we will discuss addressing modes of 8085 microprocessor. To perform any operation, we have to give the corresponding instructions to the microprocessor. In each instruction, a programmer has to specify three things: 1. Operation to be performed. 2. Address of source of data. 3. Address of destination of the result. The method … Read more
In 1834, a French scientist Peltier discovered that if the junctions are at the same temperature and a current is passed through the circuit of the Thermocouple, heat is produced at one Junction and absorbed at the other i.e. one junction (former) is heated and the other junction (later) is cooled. This is known as Peltier … Read more
Geothermal Energy Definition The energy which is generated by the temperature of the Earth and also gets stored inside the Earth is known as the geothermal energy. In the inner core of the earth, there is a layer of hot and molten rock called ‘magma’ which has temperature as high as 4,000°C. The sources of … Read more
The absorption or evolution of heat energy, if a current is allowed to flow in a conductor having its different parts of different temperatures is known as Thomson effect. or When a current flows through an unequally heated conductor, there is an absorption or evolution of heat in the body of the conductor. This is … Read more
A Wheatstone bridge is used for the accurate measurement of resistance. The Wheatstone bridge works on the principle of null deflection, i.e. the ratio of their resistances are equal, and no current flows through the galvanometer. The general arrangement of the Wheatstone bridge circuit is shown in fig. 1. It is a four arms bridge circuit … Read more
Shaded Pole Induction Motor is a type of single-phase motor consists of a stator and a cage-type rotor. It is a self-starting motor. It is also called as Shaded Pole Motor. Definition Shaded pole motor is a salient-pole, split phase type, squirrel cage rotor single phase induction motor provided with one or more auxiliary short-circuited … Read more
1. CMP R R ⇒ A, B, C, D, E, H, L, and M Instruction word size ⇒ 1 Byte Operation ⇒ When this instruction will execute the content of Register R will compare with the content of accumulator (A) and the status of flag affect accordingly to the result. Note: It is nothing but SUB R instruction and … Read more
These instructions execute on the basis of the content of accumulator. When these instructions execute, the content of accumulator will shift by 1 bit either left or right as per the instruction. 1. RLC no operand Instruction word size ⇒ 1 Byte Operation ⇒ When this instruction will execute the content of accumulator will shift (or rotate) … Read more
1. INR Rp Rp ⇒ BC ≡ B DE ≡ D HL ≡ H Instruction word size ⇒ 1 Byte Operation ⇒ When this instruction will execute the content of Register pair Rp will increase by 1 and the final result will store in the Register pair Rp. [Rp] ← [Rp] + 1LSB Addressing Mode ⇒ Register Addressing Mode 2. DCX … Read more
