Block Diagram of 8086 PRESENTED BY: D.SUKANYA(16711A0514) 2. The 20 lines of the address bus operate in multiplexed mode.


Here is the pin diagram of 8086 microprocessor − Let us now discuss the signals in detail − … architecture of 8086 microprocessor with diagram. Internal Architecture of 8086: Fig. Intel 8086 was launched in 1978. Connecting these parts together are three sets of parallel lines called buses. 4 ES. The BIU: drow the functional block diagram of 8085 microorocessor. (1) Bus Interface Unit and (2) Execution Unit . It was the first 16-bit microprocessor. The Internal Block Diagram of 8086 Microprocessor is shown below. Pipelining − 8085 doesn’t support a pipelined architecture while 8086 supports a pipelined architecture. drow the functional block diagram of 8085 microorocessor. Block of general purpose registers, 2 Block segment registers, 3 20 BIT combiner, 4 Internal bus C, 5 Queue commands, 6 The control system, 7 The control system bus, 8 Internal Bus A, 9 Arithmetic logic unit (ALU), 10 Address bus, 11 Data bus, 12 Rail Control F. Registry tags, AX -accumulator , BX - register base CX - counting register, DX - data … So the 8086 BIU will send out a 20 bit address in order to access one of the 1,048,576 or 1MB memory locations. 5. These two functional units can work simultaneously to increase system speed and hence the throughput. However it works with only four 64 KB segments within the whole 1 MB memory.

Intel 8086 was launched in 1978. 2. The 8086 was sequenced using a mixture of random logic and ... Simplified block diagram over Intel 8088 (a variant of 8086); 1=main registers; 2=segment registers and IP; 3=address adder; 4=internal address bus; 5=instruction queue; 6=control unit (very simplified! It uses a 5V DC supply for its operation. 4. I/O − 8085 can address 2^8 = 256 I/O's, whereas 8086 can access 2^16 = 65,536 I/O's. It has a 16-line data bus. Internal Architecture of 8086: Fig. Let us now discuss in detail the pin configuration of a 8086 Microprocessor.
1: Block Diagram of Intel 8086 Features of 8086 Microprocessor: 1. It was the first 16-bit microprocessor. Architecture of 8086. microprocessor is a programmable,clock-drive device. Functional Block Diagram of 8085 Microprocessor. These two functional units can work simultaneously to increase system speed and hence the throughput. 8086 was the first 16-bit microprocessor available in 40-pin DIP (Dual Inline Package) chip. Block Diagram of Intel 8086 The 8086 CPU is divided into two independent functional units: 1. Block Diagram of 8086 THE 8086 CPU IS DIVIDED INTO TWO INDEPENDENT FUNCTIONAL UNITS: o BUS INTERFACE UNIT (BIU) o EXECUTION UNIT (EU) 3. It is available as 40-pin Dual-Inline-Package (DIP). This microprocessor had major improvement over the execution speed of 8085. Block Diagram of Intel 8086 Gursharan Singh Tatla Page No. 6.2 shows a block diagram of Internal Architecture of 8086. This feature is not available right now. This microprocessor had major improvement over the execution speed of 8085. The three buses are the …
