通用數(shù)據(jù)傳送指令. MOV 傳送字或字節(jié). MOVSX 先符號擴(kuò)展,再傳送. MOVZX 先零擴(kuò)展,再傳送. PUSH 把字壓入堆棧. POP 把字彈出堆棧. PUSHA 把AX,CX,DX,BX,SP,BP,SI,DI依次壓入堆棧. POPA 把DI,SI,BP,SP,BX,DX,CX,AX依次彈出堆棧. PUSHAD 把EAX,ECX,EDX,EBX,ESP,EBP,ESI,EDI依次壓入堆棧. POPAD 把EDI,ESI,EBP,ESP,EBX,EDX,ECX,EAX依次彈出堆棧. BSWAP 交換32位寄存器里字節(jié)的順序 XCHG 交換字或字節(jié).( 至少有一個(gè)操作數(shù)為寄存器,段寄存器不可作為操作數(shù)) CMPXCHG 比較并交換操作數(shù).( 第二個(gè)操作數(shù)必須為累加器AL/AX/EAX ) XADD 先交換再累加.( 結(jié)果在第一個(gè)操作數(shù)里 ) XLAT 字節(jié)查表轉(zhuǎn)換. ── BX 指向一張 256 字節(jié)的表的起點(diǎn), AL 為表的索引值 (0-255,即 0-FFH) 返回 AL 為查表結(jié)果. ( [BX+AL]->AL )

This book uses the Python language to teach pro - gramming concepts and problem -solving skills, without assuming any previous program- ming experience. With easy-to-understand examples, pseudocode, flowcharts, and other tools, the student learns how to design the logic of programs and then implement those programs using Python. This book is ideal for an introductory programming course or a programming logic and design course using Python as the language. As with all the boolts in the Starting Out With series, the hallmark of this text is its clear, friendly, and easy -to-understand writing. In addition, it is rich in example programs that are concise and practical. The programs in this book include short examples that highlight specific programming topics, as well as more involved examples that focus on problem solving. Each chapter provides one or more case studies that provide step -by-step analysis of a specific problem and shows the student how to solve it.
