- Arithmetic Logic Unit (ALU)
- Registers (A, B, C, D, E, H, L)
- Flags (Zero, Carry, Parity, Sign)
- Instruction Register (IR)
- Program Counter (PC)
Why Gaonkar’s 8085 Text Remains the Gold Standard
Before diving into the PPT structure, it’s essential to understand why Gaonkar’s material is still requested. Unlike dry datasheets, Gaonkar’s book emphasizes:
The "Stack" Explanation
6. Stack and Subroutines (The RST Concept)
- New PPT Feature: Comparison of CALL vs JMP; using
PUSHandPOPto preserve register status. - Gaonkar’s Value: Clear explanation of the Stack Pointer (SP) initialization and how it decrements during pushes.
