8085 Microprocessor Architecture Diagram

8085 Architecture Diagram

The diagram above represents the architecture of the 8085 microprocessor, showing the various components such as the ALU, registers, and control unit.

Parts of the 8085 Microprocessor

1. Arithmetic and Logic Unit (ALU)

8085 ALU

The ALU performs arithmetic operations (addition, subtraction) and logic operations (AND, OR, XOR). It is one of the most crucial components of the microprocessor.

2. Registers

8085 Registers

Registers are small memory units within the microprocessor used to store data temporarily during processing. 8085 has several registers like the accumulator, flag register, and general-purpose registers.

3. Control Unit

8085 Control Unit

The control unit directs the operations of the processor by generating control signals and coordinating the execution of instructions in the correct order.

4. Stack Pointer (SP) and Program Counter (PC)

8085 Stack Pointer and Program Counter

The Stack Pointer and Program Counter are special purpose registers. The Stack Pointer points to the current stack location, while the Program Counter holds the address of the next instruction to be executed.
