What is the function of segment register in 8086?
Segment register ? BIU has 4 segment buses, i.e. CS, DS, SS& ES. It holds the addresses of instructions and data in memory, which are used by the processor to access memory locations. It also contains 1 pointer register IP, which holds the address of the next instruction to executed by the EU.What is the function of segment register?
A segment register changes the memory address accessed by 16 bits at a time, because its value is shifted left by 4 bits (or multiplied by 16) to cover the entire 20-bit address space. The segment register value is added to the addressing register's 16-bit value to produce the actual 20-bit memory address.- Segment Registers
Segments are specific areas defined in a program for containing data, code and stack. There are three main segments ? Code Segment ? It contains all the instructions to be executed. A 16-bit Code Segment register or CS register stores the starting address of the code segment.
