8086 processor architecture ppt
It is a 16-bit μp.
It is a 16-bit μp.
• 8086 has a 20 bit address bus can access up. to 220 memory locations (1 MB).• Word size is 16 bits and double word size is. 4 bytes.• It has multiplexed address and data bus.
AD0- AD15 and A16 – A19.• It requires single phase clock with 33% duty. cycle to provide internal timing.
What is 8086 processor architecture?
The 8086 microprocessor has a segmented memory architecture, which means that memory is divided into segments that are addressed using both a segment register and an offset.
The segment register points to the start of a segment, while the offset specifies the location of a specific byte within the segment.
