What is microprocessor and its block diagram?

Block Diagram of a Microcomputer A microprocessor consists of an ALU, control unit and register array. 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.

How many blocks are there in 8085 microprocessor?

Although the 8085 is an 8-bit processor, it has some 16-bit operations. Any of the three 16-bit register pairs (BC, DE, HL or SP) can be loaded with an immediate 16-bit value (using LXI), incremented or decremented (using INX and DCX), or added to HL (using DAD).

What are the function of 8085 microprocessor?

The architecture of the 8085 microprocessor mainly includes the timing & control unit, Arithmetic and logic unit, decoder, instruction register, interrupt control, a register array, serial input/output control. The most important part of the microprocessor is the central processing unit.

What are the basic components of microprocessor?

Microprocessor Components

• Control Unit.
• I/O Units.
• Arithmetic Logic Unit (ALU)
• Registers.
• Cache.

What are the advantages of a microprocessor?

Advantages of a microprocessor:

• The microprocessor is that these are general purpose electronics processing devices which can be programmed to execute a number of tasks.
• Compact size.
• High speed.
• Low power consumption.
• It is portable.
• It is very reliable.
• Less heat generation.
• The microprocessor is very versatile.

What is microprocessor and types?

There are three types of microprocessors namely, CISC, RISC, and EPIC. A microprocessor is basically the brain of the computer. We can also call it simply a processor or CPU. Furthermore, a microprocessor is basically a computer processor that is mounted on a single IC (Integrated Circuit).

What is the function of CISC?

A complex instruction set computer (CISC /ˈsɪsk/) is a computer in which single instructions can execute several low-level operations (such as a load from memory, an arithmetic operation, and a memory store) or are capable of multi-step operations or addressing modes within single instructions.

What are the types of microprocessor?

Microprocessors are classified into five types, namely: CISC-Complex Instruction Set Microprocessors, RISC-Reduced Instruction Set Microprocessor, ASIC- Application Specific Integrated Circuit, Superscalar Processors, DSP’s-Digital Signal Microprocessors.

What is microprocessor give example?

The Microprocessor The term microprocessor typically refers to the central processing unit (CPU) of a microcomputer, containing the arithmetic logic unit (ALU) and the control units. It is typically implemented on a single LSI chip. This separates the “brains” of the operation from the other units of the computer.

How does a microprocessor work?

How Does a Microprocessor Work? A microprocessor accepts binary data as input, processes that data, and then provides output based on the instructions stored in the memory. The data is processed using the microprocessor’s ALU (arithmetical and logical unit), control unit, and a register array.
