Microprocessor 8085: Architecture, Programming, and Applications (Based on Gaonkar)
: The internal decoder processes the instruction. No external buses are used during this internal operation. 6. Interrupts in the 8085
This article provides a comprehensive overview of the 8085 Microprocessor, structured to align with the foundational knowledge found in the definitive text, . microprocessor 8085 ppt by gaonkar new
The ALU performs arithmetic functions (addition, subtraction) and logical functions (AND, OR, XOR, Rotate). It works closely with the Accumulator, temporary registers, and the Flag Register. C. The Flag Register (Status Register)
Data is provided directly in the instruction (e.g., MVI A, 05H ). Interrupts in the 8085 This article provides a
If you find a PPT claiming to be "by Gaonkar new," check for these bonus slides that likely were added by modern educators updating the original material:
Examples: ADD B (Add contents of register B to the Accumulator), SUB C (Subtract register C from the Accumulator), INR H (Increment register H by 1). Logical Instructions subtraction) and logical functions (AND
Active-low signal indicating data on the bus is to be written to memory or an I/O device. IO/M (Pin 34): Status signal. High ( ) means an I/O operation is occurring; Low ( ) means a memory operation is occurring.
Gaonkar highlights bus optimization as a vital engineering lesson. This slide explains how the 8085 saves pin count through multiplexing and how external hardware resolves it. : Separating address and data from the shared
