作者 jenny (活在自己的世界中) 看板 NTU-Exam 標題 [試題] 97下 盧彥文 微處理機原理與應用 期中考 時間 Sat May 23 19:49:41 2009 ─────────────────────────────────────── 課程名稱︰微處理機原理與應用 課程性質︰必修 課程教師︰盧彥文 開課學院：生農 開課系所︰生機 考試日期（年月日）︰97/4/17 考試時限（分鐘）：80 是否需發放獎勵金：是 （如未明確表示，則不予發放） 試題 : problem 1(20%) briefly explain the following terms: id=odd id=even carry bit parity bit instruction MSB BCD POP Based-indexed addressing mode directives problem 2(20%): identify the addressing modes used for the source and the destination operands, as well as the maching codes in the following instructions: id=odd id=even MOV AL,BL MOV AL,BL MOV BX,0BEH MOV BX,0C3H MOV [BX][DI]+0100H,AL MOV [BX][DI]+0300H,AL problem 3(10%) express each of the following signed decimal integers as a 16-bit binary number (use 2's-complement notation for negative numbers) +20 -20 -10 +10 problem 4(8%): engineer Joe Smith worte assembly programs, which contain a Main module and a subroutine module to display a hexdecimal number on screen. Although prepared well, he found bugs in the programs. He used the 'debug' to find out the following information: AX=0000 BX=0000 CX=0010 DX=0000 SP=03FB BP=0000 SI=0000 DI=0000 DS=57D1 ES=57D1 SS=57E6 CS=57E1 IP=0013 NV UP EI PL NZ NA PO NC can you help Engineer Joe Smith find the current physical address to point to the data / the current physical address to point to the data in stack structure problem 5(15%): explain what happens when the instruction sequence that follows is executed LAHF MOV AX,1234H MOV [BX+DI],AH MOV BX,0ABCDH MOV AH,[BX+SI] CMP AX,BX SAHF assume that flags ZF,SF,CF,AF,OF,and PF are all initially reset note:(提供表格參考，就不打了) problem 6(27%): write an 8086/8088 assembly program that moves a block of N consecutive bytes of data starting at offset address ADDR1 in memory to another block of memory locations starting at offset address ADDR2. Assume that both blocks are in the same data segment, whose starting point is defined by the values DS_ADDR hint:you may use the flow chart below for this program (提供流程圖，也不打了) --
