Microprocessor 8085 Ppt By Gaonkar New Portable [ TRUSTED ✯ ]

: Overview of common support chips covered in the new Gaonkar curriculum, including the 8255 PPI (Programmable Peripheral Interface) and the 8253/8254 PIT (Programmable Interval Timer). Best Practices for Presenting this PPT

Think of the as the 8085's calculator. This is the section responsible for performing all arithmetic and logical operations on the data. When a program commands an addition, subtraction, or a logical AND , the ALU executes it.

Set to 1 if the result contains an even number of 1s (even parity).

SUB M (Subtract the contents of the memory location pointed to by HL from the Accumulator) INR D (Increment the contents of register D by 1) 3. Logical Operations microprocessor 8085 ppt by gaonkar new

: The address is held within a register pair, usually HL (e.g., MOV A, M ).

An 8-bit register that serves as the primary location for arithmetic and logical operations. It holds one of the operands and stores the final result.

The 8085 possesses 8 built-in software instructions that force the program vector to specific memory locations: . They multiply the interrupt index integer by 8 to determine their precise Vector Address (e.g., RST 4 vectors to , which is in hexadecimal format). 7. Slide Deck Outline for Presentations : Overview of common support chips covered in

Ramesh Gaonkar’s textbooks are famous because they don't just list facts; they explain the . Understanding how the Address Latch Enable (ALE) signal works to demultiplex the AD0-AD7 bus is the "aha!" moment for most students.

Mind map or categorised branches of 8085 instructions. Core Content:

: Set if a carry is generated from bit D3 to D4 during arithmetic. When a program commands an addition, subtraction, or

A 16-bit register pointing to the current top of the stack memory area. Slide 5: The Status Flag Register

One precise sub-division of an operation corresponding to one internal clock pulse period.

Ramesh Gaonkar categorizes the 8085 instruction set into five functional domains based on the operations they execute. Data Transfer Instructions

Raj ran a hand through his hair, staring at the blank projector screen. "We can’t rewrite a whole presentation on the 8085 by morning. We don’t have the notes on the flag registers or the interrupt priority matrix."
