Ramesh Gaonkar’s approach is favored because he bridges the gap between hardware and software. His diagrams are clear, and his explanation of (showing how Machine Cycles and T-states work) is unparalleled for beginners. How to Find a Free 8085 PPT by Gaonkar
Instructions like HLT (Halt) or NOP (No Operation). 4. Memory Interfacing and I/O
A 16-bit register that points to the memory address of the next instruction to be executed. microprocessor 8085 ppt by gaonkar free
Moving data between registers or between memory and registers (e.g., MOV , MVI , LXI ).
The 8085 is an 8-bit general-purpose microprocessor capable of addressing 64 KB of memory. Developed by Intel in the mid-1970s, it is a classic example of . Key Specifications: Data Bus: 8-bit (carries data between the CPU and memory). Address Bus: 16-bit (can address memory locations). Clock Speed: Typically 3 MHz. Technology: NMOS, requiring a single +5V power supply. 2. Architecture and Register Organization Ramesh Gaonkar’s approach is favored because he bridges
Gaonkar emphasizes the internal block diagram, which is the heart of any 8085 presentation.
Contains five status flags: Carry (CY), Parity (P), Auxiliary Carry (AC), Zero (Z), and Sign (S). 3. The 8085 Instruction Set The 8085 is an 8-bit general-purpose microprocessor capable
Six registers (B, C, D, E, H, and L) that can be used individually or in pairs (BC, DE, HL) to store 16-bit data.
AND, OR, XOR, compare, and rotate (e.g., ANA , ORA , RLC ). Branching: Jump, Call, and Return (e.g., JMP , CALL , RET ).
