Microprocessor 8085 Ppt By Gaonkar -

The ALU performs arithmetic operations (addition, subtraction) and logical operations (AND, OR, XOR). The is an 8-bit register directly tied to the ALU. It holds one of the operands for ALU operations and serves as the destination for the resulting output. General-Purpose Registers

The 8085 is an 8-bit, general-purpose microprocessor capable of addressing . It was designed to be binary compatible with the earlier 8080 but with a simplified hardware design, requiring only a single +5V power supply.

Microprocessor Architecture, Programming, and Applications with the 8085

Set to 1 if the ALU operation result is exactly zero. microprocessor 8085 ppt by gaonkar

distinguishes between I/O operations (High) and Memory operations (Low). Combined with S1 and S2, they define the exact operational state (e.g., Opcode Fetch, Memory Read, Memory Write).

(Write; active low) manage data flow between the processor and external memory or peripherals.

Gaonkar’s book is famous for his "Instruction Set" appendix. If you want to make your PPT practical, include a slide on Addressing Modes (Immediate, Direct, Register, Indirect). He explains these as "how we find the data," which is intuitive for beginners.

: Typically runs at a maximum frequency of 3 MHz . Power Requirement : Operates on a single +5V DC supply. This link or copies made by others cannot be deleted

The visual heavy-lifting happens in this section. A slide would likely feature a detailed block diagram of the 8085's internal structure, breaking it down into its key functional units.

This foundation remains indispensable for embedded systems design, robotics controllers, and firmware engineering. Key Tips for Delivery (Instructor Notes)

At the beginning of a machine cycle, the 8085 places the lower 8 bits of the address on and drives the pin high.

Weaknesses

is the definitive academic resource for understanding 8-bit computing. His work bridges the gap between hardware theory and assembly language programming, making it the standard for undergraduate engineering PPTs and study materials. The Architecture of 8085

: Moving data between registers or memory (e.g., MOV , MVI ).

Create a slide specifically for the Flag Register (S, Z, AC, P, CY) as this is a favorite exam topic.

Lowest priority, non-vectored, maskable interrupt requiring an external hardware device to supply an opcode instruction byte (usually RST or CALL ). Combined with S1 and S2
