What is offset address 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. A 16-bit offset is always added to the 20-bit segment address to yield an external address.
What is mean by offset address?
In computer engineering and low-level programming (such as assembly language), an offset usually denotes the number of address locations added to a base address in order to get to a specific absolute address. In this context an offset is sometimes called a relative address.
What is the offset address of code segment?
A Segment Offset Address combines the starting address of a segment with an offset value. Segment and offset: Segments are special area defined in a program for containing the code, the data, and the stack.
How is offset address calculated?
The offset of the CS Register is the IP register. Ans: The address calculated when BP is taken as the offset gives the starting address of the stack. The address when SP is taken as the offset denotes the memory location where the top of the stack lies.
Which register holds the offset address?
Stack pointer
What is a logical address space?
Logical Address Space is the set of all logical addresses generated by CPU for a program whereas the set of all physical address mapped to corresponding logical addresses is called Physical Address Space.
Why do we need logical address?
Logical address is used to reference to access the physical memory location. A logical address is generated so that a user program never directly access the physical memory and the process donot occupies memory which is acquired by another process thus corrupting that process.
What is difference between logical and physical address space?
The basic difference between Logical and physical address is that Logical address is generated by CPU in perspective of a program. On the other hand, the physical address is a location that exists in the memory unit. The set of all logical addresses generated by CPU for a program is called Logical Address Space.
Can I have a virtual address?
