What is physical address in 8086?
The 8086 processor has a 20-bit address bus, which gives a physical address space of up to 1 MB (2²⁰), addressed as 00000h to FFFFFh.
How is physical address generated in 8086 based system?
To access a specific memory location from any segment we need 20- bit physical address. The 8086 generates this address using the contents of segment register and the offset register associated with it. The BIU has a dedicated adder for determining physical memory address.
What is the physical memory of 8086?
The CPU 8086 is able to address 1 Mbytes of physical memory. The complete 1 Mbytes memory can be divided into 16 segments, each of 64 Kbytes size.
In computing, a physical address (also real address, or binary address), is a memory address that is represented in the form of a binary number on the address bus circuitry in order to enable the data bus to access a particular storage cell of main memory, or a register of memory-mapped I/O device.
