Microprocessor 8085 Ppt By Gaonkar ~upd~ -

The power of the 8085 lies in its ability to interact with the outside world. Memory Interfacing

ALE (Address Latch Enable): Used to demultiplex the AD0–AD7 bus.

Ramesh Gaonkar’s pedagogy focuses on the transition from hardware logic to software execution. His method emphasizes: Visualizing the timing diagrams. Understanding the "Fetch-Decode-Execute" cycle. Hands-on assembly language programming. microprocessor 8085 ppt by gaonkar

These move data between registers or between memory and registers. Example: MOV A, B (Move content of B to A). Arithmetic and Logical Instructions Used for calculations and bitwise manipulation.

The ALU performs all numerical and logical operations. These include addition, subtraction, AND, OR, and XOR. It uses data from the Accumulator and temporary registers to generate results. The power of the 8085 lies in its

The Intel 8085 is a landmark in the history of computing. Developed as an enhancement of the 8080, it became the foundation for teaching computer architecture. This guide follows the curriculum and structural style popularized by Ramesh Gaonkar, the leading authority on 8085 instruction and interfacing. Introduction to the 8085 Microprocessor

The 8085 interfaces with EPROM (for program storage) and RAM (for temporary data). Decoders like the 74LS138 are often used to map specific addresses to these chips. I/O Interfacing Peripheral-Mapped I/O: Uses IN and OUT instructions. Memory-Mapped I/O: Treats I/O devices as memory locations. Why Gaonkar's Approach? His method emphasizes: Visualizing the timing diagrams

The architecture is divided into several functional units that work in sync to execute instructions. The Arithmetic Logic Unit (ALU)

Example: ADD B (Add B to Accumulator), ANA C (Logical AND C with Accumulator). Branching Instructions These alter the flow of the program. Example: JMP 2000H (Jump to address 2000H), CALL , and RET . Interfacing and Applications

Program Counter (PC): A 16-bit register that points to the next instruction address.
