Instruction set of 8086 Microprocessor
Converting Assembly Language Instructions to Machine Code • An instruction can be coded with 1 to 6 bytes • Byte 1 contains three kinds of information – Opcode field (6 bits) specifies the operation (add, subtract, move) – Register Direction Bit (D bit) Tells the register operand in REG field in byte 2 is source or destination operand

11 KV Substation.
www.bsiet.org3. The 11 kV line is connected to the transformer (11kV / 400 V) through gang isolator and fuses. 4. The lightning arresters are installed on the H.T. side to protect the sub-station from lightning strokes. 5. The transformer steps down the voltage to 400V, 3-phase, 4-wire supply. The voltage

www.bsiet.orgvessel. These accumulated vapors exert pressure on the liquid surface. This pressure is known as vapor pressure of the liquid or this is the pressure at which the liquid is converted into vapors. 2.10 Compressibility and bulk modulus -Bulk modulus is defined as the ratio of compressive stress (increase in pressure) to volumetric strain.

amber.feld.cvut.czlanguage and its associated assembly language are completely machine dependent . – In other words, they are not transferable from one microprocessor to a different one. • For example, Motorolla has an 8- bit microprocessor called the 6800. – The 8085 machine language is very different from that of the 6800. So is the assembly language.
