Block Diagram 8086

Decoder in the eu translates instructions fetched from the memory into a series of actions.

Block diagram 8086. It was the first 16 bit microprocessor. The following diagram depicts the architecture of a 8086. These two functional units can work simultaneously to increase system speed and hence the throughput. As discussed earlier the 8086 microprocessor consists of two main blocks.

Execution unit gives instructions to biu stating from where to fetch the data and then decode and execute those instructions. Features of 8086 microprocessor. It is internally divided into two separate functional units. It is available in three versions.

It was the first 16 bit microprocessor. 6 2 shows a block diagram of internal architecture of 8086. Intel 8086 was launched in 1978. Intel 8086 was launched in 1978.

Instruction decoder alu. The figure below shows the block diagram of the architectural representation of the 8086 microprocessor. This microprocessor had major improvement over the execution speed of 8085. It is available in 40 pin dip chip.

These are set or reset by the eu on the basis of the results of some arithmetic or logic. Block diagram of intel 8086. We will first see a block diagram explaining the layout of the components of the microprocessor and will then explain the diagram briefly describing each of its components. It uses a 5v dc supply for its operation.

Internal architecture of 8086. Block diagram of intel 8086 the 8086 cpu is divided into two independent functional units. Here is the pin diagram of 8086 microprocessor let us now discuss the signals in detail power supply and frequency signals. The following diagram depicts the architecture of a 8086 microprocessor 8086 microprocessor is divided into two functional units i e eu execution unit and biu bus inter face unit.

Pipelining 8085 doesn t support a pipelined architecture while 8086 supports a pipelined architecture. Bus interface unit biu 2. Bus interface unit biu. The 20 lines of the address bus operate in multiplexed mode.

Block diagram of 8086 microprocessor the architecture of 8086 microprocessor is composed of 2 major units the biu i e bus interface unit and eu i e execution unit. Cost the cost of 8085 is low whereas that of 8086 is high. Pin diagram of 8086 microprocessor is as given below. 8086 was the first 16 bit microprocessor available in 40 pin dip dual inline package chip.

Execution unit eu fig. It is available as 40 pin dual inline package dip. It has a 16 line data bus. Functional block diagram of 8086 microprocessor eu.

The bus interface unit biu and the execution unit eu. I o 8085 can address 2 8 256 i o s whereas 8086 can access 2 16 65 536 i o s. These are the bus interface unit biu and the execution unit eu. Block diagram of intel 8086 features of 8086 microprocessor.
