Set to 1 if the ALU operation result is exactly zero.
The 8085 microprocessor remains a foundational subject in computer engineering and electronics education. Ramesh S. Gaonkar’s textbook, " Microprocessor Architecture, Programming, and Applications with the 8085, " is the definitive text on the subject, frequently used to structure comprehensive PPT presentations for students and professionals. This article provides a detailed breakdown of the 8085 microprocessor, covering its architecture, programming, and key concepts, designed for a modern "new" presentation format based on Gaonkar's teachings. 1. Introduction to the 8085 Microprocessor microprocessor 8085 ppt by gaonkar new
Set to 1 if the most significant bit (D7) of the result is 1 (negative number).
A 16-bit register that manages the stack memory, crucial for subroutine handling.
The exact 16-bit memory address of the target data is written inside the instruction (e.g., STA 3000H ). Hardware interrupts include (Non-maskable), RST 7
The 8085 uses multiplexed buses to save pin space, a key topic in Gaonkar’s text: A 16-bit bus used to address KB of memory. Data Bus ( D0cap D sub 0 D7cap D sub 7 ): An 8-bit bidirectional bus used to transfer data. Multiplexed Bus ( AD0cap A cap D sub 0 AD7cap A cap D sub 7
) : Define the type of machine cycle currently in progress (e.g., Fetch, Read, Write, Halt).
To make your PowerPoint engaging, include simple assembly language programs with step-by-step commentary. Example A: Addition of Two 8-bit Numbers Ramesh S
Raj leaned in. He had spent weeks trying to memorize the pin configurations, but looking at Gaonkar’s diagrams in the old book, the confusion cleared. The book didn't just list facts; it told a narrative of how the Program Counter (PC) guided the processor, and how the Stack Pointer remembered where it had been.
The 8085 features a matrix of registers accessible to the programmer:
These operations alter the sequential flow of program execution by changing the value of the Program Counter. They can be unconditional or conditional (dependent on status flags). JMP 3000H (Unconditionally jump to memory address 3000H) JC 2500H (Jump to 2500H only if the Carry flag is set to 1) CALL 4000H (Call subroutine located at 4000H) 5. Machine Control and I/O Operations
: Use Gaonkar's clear terminology like "Microprocessing Unit (MPU)" instead of just "CPU" to match standard examination vocabularies.
