Before we dive into the details of the book, let us first understand what is 8085 microprocessor, who is Ramesh Gaonkar, and why is this book important.

What is 8085 microprocessor?

A microprocessor is a small electronic device that can perform arithmetic and logic operations on binary data. It is the brain of a computer system that controls all its functions. A microprocessor consists of three main components: an arithmetic logic unit (ALU), a control unit (CU), and a set of registers.

The 8085 microprocessor is an 8-bit microprocessor that was designed by Intel in 1976. It can execute up to 74 instructions with different addressing modes. It has a clock speed of 3 MHz and can access up to 64 KB of memory. It has five hardware interrupts and one software interrupt. It uses a single +5V power supply and has a low power consumption.

Who is Ramesh Gaonkar?

Ramesh Gaonkar is a professor of electrical engineering at Purdue University Northwest in Indiana, USA. He has over 40 years of teaching and research experience in the field of microprocessors and embedded systems. He has authored several books and papers on these topics. He has also received many awards and honors for his contributions to engineering education.

Why is this book important?

The book "Microprocessor Architecture, Programming, and Applications with the 8085" by Ramesh Gaonkar is one of the most widely used textbooks on microprocessors.
