How is the base effective register address determined?
Base register addressing mode:Base register addressing mode is used to implement inter segment transfer of control.In this mode effective address is obtained by adding base register value to address field value. EA= Base register + Address field value. PC= Base register + Relative value.
What is the need of the base register?

What is a base address register?
A Base Address Register (BAR) is used to: – specify how much memory a device wants to be mapped into main memory, and. – after device enumeration, it holds the (base) address, where the mapped memory block begins. A device can have up to six 32-bit BARs or combine two BARs to a 64-bit BAR.
