Execution Unit (EU) and Bus Interface Unit (BIU) :

8086 consist of two processors called EU and BIU. Two Processors can work parallel. This improves speed of execution. BIU first fetches instruction and place them in the instruction queue.

Execution unit decodes and execute instruction.  When EU is executing an instructionthenBIU can fetch the next instruction.
