Microprocessor 8085 Ppt By Gaonkar ((new)) Jun 2026

Understanding the physical pins, registers, and internal buses.

An 8-bit register containing 5 active flags (Sign, Zero, Auxiliary Carry, Parity, Carry).

16-bit wide. This allows the processor to address memory locations (64 KB).

Comprehensive guide based on Ramesh Gaonkar's standard textbook framework. microprocessor 8085 ppt by gaonkar

CMA (Complement the contents of the Accumulator by inverting all bits) 4. Branch Control Group

Data is transferred between registers (e.g., MOV A, B ).

Alters the normal linear sequence of a program conditionally or unconditionally (e.g., JMP , JC , CALL , RET ). This allows the processor to address memory locations

Each of these weekly topics is broken down into detailed PowerPoint slides, providing a comprehensive learning resource. The core technical content found across these presentations is extensive and covers a broad range of topics, from fundamental concepts to advanced programming and system design.

The internet is flooded with poor-quality, plagiarized slides. Here is where to find legitimate resources:

The flag register is an 8-bit register containing five active 1-bit flip-flops that indicate the conditional status of the ALU after an operation: Bit Position Description D7cap D sub 7 Sign Flag ( Set to 1 if the MSB ( D7cap D sub 7 ) of the result is 1 (negative number). D6cap D sub 6 Zero Flag ( Branch Control Group Data is transferred between registers

If you’ve ever studied electronics or computer science, you know that book is the ultimate bible for understanding the 8085 architecture.

Avoid PPTs that only show screenshots of the textbook. A good PPT uses bullet points and minimal text, explaining the concept in the presenter's own words .

You can find these valuable PPT resources on major slide-sharing websites.
