TAILIEUCHUNG - Lecture Computer organization and assembly language - Lecture 12: Addressing Modes in Assembly

This chapter define the terms bitmap and vector and differentiate these file types, list some of the most commonly used file formats for bitmap and vector Images, identify four ways to load graphic files into a computer, list five types of graphics software and their uses, define the terms multimedia and interactivity. | CSC 221 Computer Organization and Assembly Language Lecture 12: Addressing Modes in Assembly Lecture 11: Review OFFSET Operator OFFSET returns the distance in bytes, of a label from the beginning of its enclosing segment PTR Operator Overrides the default type of a label (variable). Provides the flexibility to access part of a variable. mov esi,OFFSET bVal ;ESI = 00404000 -------------------------------- .data array BYTE 100 DUP(?) .code mov esi,OFFSET array ; ESI is p Data-Related Operators and Directives .data myBytes BYTE 12h,34h,56h,78h .code mov ax,WORD PTR [myBytes] mov ax,WORD PTR [myBytes+2] mov eax,DWORD PTR myBytes Lecture 11: Review TYPE Operator The TYPE operator returns the size, in bytes, of a single element of a data declaration. LENGTHOF Operator The LENGTHOF operator counts the number of elements in a single data declaration.
