Both units operate asynchronously to give. 8086 has two blocks Bus interface unit (BIU) and Execution Unit (EU). It can pre-fetches up to 6 instruction bytes from memory and queues them in order to
It requires single phase clock with 33% duty cycle to provide internal timing.Ĩ086 is designed to operate in two modes, Minimum and Maximum. It operates at 5 MHz Clock and also 8 and 10 MHz It has multiplexed address and data bus AD0- AD15 and A16 – A19. It can access upto 220 = 1,048,567 ( 1 MB) memory locations It is a 16 bit μp with 20 bit address bus and 16 bit data bus. Internal hardware architecture of 8086 microprocessor with neat diagram.
