Ramesh S. Gaonkar’s textbook, Microprocessor Architecture, Programming, and Applications with the 8085 , is widely considered the definitive resource for understanding the 8085 microprocessor. His teaching methodology, often summarized in modern classroom presentations, emphasizes an integrated approach where hardware architecture and assembly language programming are taught as a single, cohesive system. Slide 4: Demultiplexing the Bus and Generating Control

Set to 1 if the ALU operation results in exactly 0. Set to 1 if the ALU operation results in exactly 0

Includes opcode and operand in a single byte (e.g., MOV A, B , ADD C ).

The internal architecture of the 8085 is designed to fetch, decode, and execute instructions. Key components include: A. The ALU (Arithmetic Logic Unit) The ALU performs 8-bit arithmetic ( ) and logical ( ) operations. B. Registers

during addition. Used for Binary Coded Decimal (BCD) operations.
