Microprocessor 8085 Ppt By Gaonkar - New
Doc opened the book. It wasn't just text; it was a visual symphony of logic. He pointed to a diagram of the internal architecture.
: Embeds the raw operand data directly inside the instruction byte string (e.g., MVI A, 05H ).
: A complete, functional computing system that integrates a microprocessor unit with external memory (RAM/ROM) and Input/Output (I/O) ports. microprocessor 8085 ppt by gaonkar new
Instruction Set Classification (The 5 Gaonkar Groups)
The 8085 microprocessor, designed by Intel in the late 1970s, remains a cornerstone in computer engineering education. Despite the advent of modern 64-bit processors, the 8085 provides the perfect pedagogical introduction to how computers actually work at the hardware level. Doc opened the book
Because the low-order address bus and data bus share the same physical pins, they must be separated externally:
Instructions that manage system status or control hardware interface lines. IN 01H (Input data from port 01H into the Accumulator) OUT 02H (Output data from the Accumulator to port 02H) HLT (Halt further instruction execution) 5. Memory Interfacing and Demultiplexing the Bus : Embeds the raw operand data directly inside
: Details on the 8-bit data bus, 16-bit address bus (64KB memory addressing), and 40-pin IC package.
The 8085 is housed in a 40-pin Dual In-line Package (DIP). A key concept emphasized in Gaonkar's presentations is , which minimizes the physical pin count.
