What is 8085microprocessor?
The Intel 8085 (“eighty-eighty-five”) is an 8-bit microprocessor produced by Intel and introduced in March 1976. It is software-binary compatible with the more-famous Intel 8080 with only two minor instructions added to support its added interrupt and serial input/output features.
What is microprocessor and its block diagram?
Block Diagram of a Microcomputer Where ALU performs arithmetic and logical operations on the data received from an input device or memory. Control unit controls the instructions and flow of data within the computer. And, register array consists of registers identified by letters like B, C, D, E, H, L, and accumulator.
Which software is used for microprocessor?
Keil uVision is one of the tools that is used in the programming of the microcontrollers. The software is an integrated development environment (IDE) that integrated a text editor to write programs, a compiler, and converts source code into a hex file.
What is flag register in 8085 microprocessor?
Prerequisite – Registers of 8085 microprocessor The Flag register is a Special Purpose Register. Depending upon the value of the result after any arithmetic and logical operation, the flag bits become set (1) or reset (0). In 8085 microprocessor, the flag register consists of 8 bits and only 5 of them are useful.
What is microprocessor PDF?
A microprocessor is a controlling unit of a micro-computer, fabricated on a small chip capable of performing Arithmetic Logical Unit (ALU) operations and communicating with the other devices connected to it. In this tutorial, we will discuss the architecture, pin diagram and other key concepts of microprocessors.
What is the function of Sim instruction in 8085?
In 8085 Instruction set, SIM (Set Interrupt Mask) and RIM (Read Interrupt Mask) instructions can perform mask and unmask RST7. 5, RST6. 5, and RST5. 5 interrupt pins and can also read their status.
What is microprocessor coding?
An essential tool for programming a microprocessor is an Integrated Development Environment (IDE). This is software that is developed by the creators of the microprocessors which will compile the code into a language the machine can understand. Once you have an IDE setup, you can begin writing your code.
Is microprocessor A hardware?
The hardware subsystem is composed of the microprocessor, the memory devices, the peripheral (or I/O) devices and the media used to connect each of these.
