[base + index] (cont.) .data array WORD 1000h,2000h,3000h .code mov ebx,OFFSET array mov esi,2 mov ax,[ebx+esi] ; AX = 2000h mov edi,OFFSET array mov ecx,4 mov ax,[edi+ecx] ; AX = 3000h mov ebp,OFFSET array mov esi,0 mov ax,[ebp+esi] ; AX = 1000h Lecture 27: Review Base-Index Displacement A base-index-displacement operand adds base and index registers to a constant, producing an effective address. Displacement can be the name of a variable or a constant expression. (cont.) [ base + index + displacement ] displacement [ base + index ] RowNumber = 1 ColumnNumber = 2 mov ebx,NumCols * RowNumber mov esi,ColumnNumber mov .
