TAILIEUCHUNG - Lecture Computer organization and assembly language - Lecture 10: Data Transfer, Add & SUB (Flags)

This lesson looks at the processors most commonly found in personal computers and describes some of their most important features and distinguishing characteristics. You will learn how these CPUs arc typically differentiated from one another and sec how their performance is measured. You also will learn some of the ways you can extend the power of your PC’s processor to other components by using its expansion capabilities. | CSC 221 Computer Organization and Assembly Language Lecture 10: Data Transfer, Add & SUB (Flags) (In Assembly) Lecture 09: Review Data Transfer Instructions Operand Types Instruction Operand Notation Direct Memory Operands MOV Instruction Zero & Sign Extension XCHG Instruction Direct-Offset Instructions Direct Memory Operands .data var1 BYTE 10h .code mov al,var1 ; AL = 10h mov al,[var1] ; AL = 10h Lecture 09: Review (cont.)
