Microprocessor 8085 Ppt By Gaonkar New Best Jun 2026

Addition, subtraction, increment/decrement (e.g., ADD , SUB , INR ).

: An 8-bit primary register that holds one of the operands for ALU operations and stores the final execution result. General-Purpose Registers : Six 8-bit registers (

These operations perform mathematical calculations. All actions occur relative to the accumulator. ADD B (Add contents of register B to the Accumulator)

An 8-bit register that serves as one of the primary inputs for ALU operations and holds the final result of most calculations. microprocessor 8085 ppt by gaonkar new

Addressing modes define how the operand is specified. Gaonkar classifies them into five types:

) and transition to carrying data bytes during subsequent clock cycles ( Demultiplexing using Address Latch Enable (ALE)

Six 8-bit registers— B, C, D, E, H, and L . They can be used individually or paired together ( BC, DE, HL ) to function as 16-bit registers. The HL pair frequently acts as a memory pointer. Addition, subtraction, increment/decrement (e

The highest priority interrupt. It is non-maskable (cannot be disabled by software) and uses edge-and-level triggering. It is reserved for critical events like sudden system power failures.

Gaonkar divides the 8085 architecture into three main functional segments to facilitate understanding, which are essential for any PPT presentation: A. Register Array All actions occur relative to the accumulator

The Arithmetic Logic Unit performs operations like addition, subtraction, AND, OR, and XOR. It works closely with the , which indicates the status of the result (Zero, Carry, Sign, etc.). 3. Timing and Control Unit

: Conditional and unconditional jumps, calls, and returns (e.g., JNZcap J cap N cap Z CALLcap C cap A cap L cap L Machine Control : Instructions like HLTcap H cap L cap T NOPcap N cap O cap P

These operations perform mathematical calculations, automatically updating the status flags based on the output.

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.
