What is the reason for naming microprocessor as 8085 and microcontroller as 8051?
b/c the 8085 microprocessor is the first 8 bit microprocessor which Intel is produces in 1877 and this is the first general purpose 8 bit microprocessor. there was an 8 bit general purpose register before 8085 named as 8008 but this microprocessor is not functional 8 bit microprocessor
How many bits in 8085 microprocessor?
The 8085 is an 8-bit microprocessor. Even though there are some 16-bit registers (BC, DE, HL, SP, PC), with some 16-bit operations that can be performed on them, and a 16-bit address bus, the accumulator (A), the arithmetic logic unit (ALU), and the data bus are 8-bits in size, making the 8085 an 8-bit computer.
Why the shape of block of alu is different from other blocks in block diagram of microprocessor 8085?
In the block diagram of the 8085 microprocessor, the shape of the ALU (Arithmetic Logic Unit) block is often depicted differently to highlight its distinct functional role. The ALU is responsible for performing arithmetic and logic operations, making it a critical component that processes data. Its unique shape visually distinguishes it from other blocks, such as registers and control units, which have different functions within the microprocessor architecture. This differentiation aids in understanding the overall design and operation of the microprocessor.
Why is an microprocessor so named?
Microprocessor is a combined term meaning small (micro) central processing unit (CPU), usually on one chip. An example is the 8085 or 8086/8088.Contrast this with microcomputer, which is a microprocessor that also includes ROM, RAM, and IO on the chip. An example is the 87C51.
Parts of the central processing unit?
The central processing unit (CPU) IS the brain of the computer.
What is the structure of each microprocessors?
the structure of microprocessor consists of ALU, Register array unit and control unit.
What are the parts of a microprocessor?
The microprocessor contains the CPU of a microcomputer. It is composed of the Arithmetic Logic Unit, Cache Memory (optional), Memory Management Unit (optional), Bus Interface Unit, Control Unit, Instruction Decoder, and Registers.
What is the name of the temporary microprocessor storage locations used by the control unit?
Register
What unit can be called the brain of a computer microprocessor?
Control unit .Because it controls or supervises the all the actions of computer by generating control signals .
Block diagram of 8085 mpu and describe different parts of it?
The block diagram of the 8085 microprocessor (MPU) consists of several key components: the Arithmetic Logic Unit (ALU), registers, control unit, instruction decoder, and buses (address bus, data bus, and control bus). The ALU performs arithmetic and logical operations, while registers temporarily store data and instructions. The control unit manages the flow of data within the MPU and coordinates its operations. The buses facilitate communication between the MPU and memory or input/output devices, with the address bus carrying memory addresses, the data bus transferring data, and the control bus managing signals for operations.
What part of the CPU stores program instructions during the execution of the program?
the microprocessor
How 8085 work?
The 8085 microprocessor is an 8-bit CPU that operates on a 16-bit address bus, allowing it to access up to 64KB of memory. It executes instructions stored in memory by fetching them, decoding them, and then executing them using its internal registers and arithmetic logic unit (ALU). The 8085 supports various operations, including arithmetic, logic, control, and data transfer instructions. It also features integrated interrupts and a simple I/O interface, enabling it to interact with peripheral devices.
