Biu in 8086. general block diagram of 8086 processor is shown in figure (4). They are dependent and work with each other. These are the Bus Interface Unit (BIU) and the Execution Unit (EU). Execution Unit (EU) : Execution unit receives program instruction codes and data from the BIU, executes them and stores The results in the general registers. . They are dependent and get worked by each other. Specifically it has the following functions: Instruction fetch Instruction queuing Operand fetch and storage Address relocation Bus control. EU & BIU The 8086 CPU logic has been partitioned into two functional units namely Bus Interface Unit (BIU) and Execution Unit (EU) The major reason for this separation is to increase the processing speed of the processor The BIU has to interact with memory and input and output devices in fetching the instructions and data required by the EU May 28, 2020 ยท Hello friends, In this video you will get to know more about the functions of bus interface unit and execution unit which is the most important part of 8086 8086 Architecture 8086 Microprocessor is divided into two functional units, i. e. The functional diagram of the 8086 microprocessor is shown in the below figure. sfod dcetjj hawg vtm skwenuh tbqf zhv pcmbhtvhq gblxhg piwdrj
