Loading a piece of data from memory into the CPU's register, all instructions must be fetched before they can be executed. This process can be achieved in the bus interface unit by using the address conversion mechanism in which the 16-bits stack segment register is shifted to the left hand side a nibble to extend it to 20-bits address. Now, having an arbitrary binary stack segment register 1010101010101111b and its stack pointer offset 11001111b, depicted in figure below, find the physical address location in hexadecimal format. 20 LINES-ADDRESS BUS BIU ADDRESS CONVERSION Data ADD(3) ADD(2) ADD(1) ADD(0) MECHANISM PA Data ADD(3) ADD(2) ADD(1) ADD(0) SP SS S SP 11001111b Data ADD(3) ADD(2) ADD(1) ADD(0) 1010101010101111b Stack Segment MEMORY (RAM)
