Write a program to add two 16-bit numbers stored in memory locations (2000H, 2001H) and (2002H, 2003H). Store the result in 2004H (low byte) and 2005H (high byte).
For decades, Ramesh S. Gaonkar’s (published by Prentice Hall/Penram International) has served as the undisputed "bible" for understanding microprocessors.
If you are looking to build a career in embedded systems, IoT, or robotics, having the of Gaonkar on your shelf is an absolute necessity.
Ramesh Gaonkar’s "Microprocessor Architecture, Programming, and Applications with the 8085" is more than just a textbook; it is a rite of passage for hardware enthusiasts. It strips away the layers of abstraction found in modern computing, allowing the reader to understand the pulse of the machine. Whether you are a student preparing for exams or a hobbyist looking to understand the "soul" of a computer, this book remains an essential addition to your technical library. Share public link
– These chapters are gold. Gaonkar covers:
A robust set of exercises that range from basic logic gates to complex system design.
The pathways (Address, Data, and Control) that connect the CPU to the outside world.
Instructions like HLT (Halt) and NOP (No Operation) manage the state of the processor itself. 4. Hardware Interfacing and the System Bus
– Include the complete 8085 instruction set in hex order, instruction execution times (T-states), and answers to selected problems.
Set if the most significant bit (D7) of the result is 1.
– A deep dive into the 8085’s five interrupts (TRAP, RST 7.5, RST 6.5, RST 5.5, INTR). The 2014 edition includes modern equivalents like vectored interrupt controllers.
Ramesh Gaonkar’s work is more than a textbook; it is a rite of passage for electrical and computer engineers. By mastering the 8085 through this guide, you develop a "low-level" intuition that makes learning modern languages like C++, Python, or Rust significantly easier. You stop seeing code as magic and start seeing it as a precise sequence of electrical states.
Focuses on advanced interfacing with programmable devices like the (Timer), and (Interrupt Controller).
: Addition, subtraction, incrementing, and decrementing (e.g., ADD , SUB , INR , DCR ).
