2. What is Microprocessor??? Microprocessor: A silicon chip that contains a CPU. In the world of personal computers, the terms microprocessor and CPU are used interchangeably. A microprocessor (sometimes abbreviated µP) is a digital electronic component with miniaturized transistors on a single semiconductor integrated circuit (IC).

3. What is Microprocessor??? At the heart of all personal computers and most working stations sits a microprocessor. Microprocessors also control the logic of almost all digital devices, from clock radios to fuel-injection systems for automobiles. Three basic characteristics differentiate microprocessors: Instruction set: The set of instructions that the microprocessor can execute. Bandwidth : The number of bits processed in a single instruction. Clock speed: Given in megahertz (MHz), the clock speed determines how many instructions per second the processor can execute.

4. MOV Instruction (MOV Rd,Rs) MOV Rd,Rs MNEMONIC MOV Rd,Rs OPERATION Rd = Rs NO. OF BYTES 1 BYTE MACHINE CYCLE 1(OF) ALGORITHM Rd ← Rs FLAGS No flags are affected ADDRESING MODE Register addressing mode. T-STATES 4

5. MOV Instruction (MOV Rd,Rs) Description This instruction copies the data from source register Rs to the destination register Rd. The content of source register remain unchanged. Example: MOV B,C (This instruction will copy the contents of register C to register B)

6. MOV Instruction (MOV Rd,Rs) Program: Write an ALP to interchange value the 8-bit data stored in register B and C. MEMORY ADDRESS MNEMONIC NO. OF BYTES B000H MOV H,B 1 B001H MOV L,C 1 B002H MOV C,H 1 B003H MOC B,L 1

8. MOV Instruction (MOV R,M) MOV R,M MNEMONIC MOV R,M OPERATION R = M or R=(HL) NO. OF BYTES 1 BYTE MACHINE CYCLE 2(OF + MR) ALGORITHM R ← M FLAGS No flags are affected ADDRESING MODE Indirect addressing mode. T-STATES 4 + 3 = 7

9. MOV Instruction (MOV R,M) Description This instruction copies the data from memory M (pointed by HL pair) to the destination register R. The content of source register remain unchanged. Example: MOV B,M (This instruction will copy the contents of memory location pointed by HL pair to register B)

11. MOV Instruction (MOV M,R) MOV M,R MNEMONIC MOV M,R OPERATION M = R or (HL) = R NO. OF BYTES 1 BYTE MACHINE CYCLE 2(OF + MW) ALGORITHM M ← R FLAGS No flags are affected ADDRESING MODE Indirect addressing mode. T-STATES 4 + 3 = 7

12. MOV Instruction (MOV M,R) Description This instruction copies the data from register R to memory M (pointed by HL pair). The content of source register remain unchanged. Example: MOV M,B (This instruction will copy the contents of register B to memory location pointed by HL pair.)
