1.- A) Express each of the signed decimal integersthat follow as either a byte- or a word hexadecimal number (use2's-complement notation for negative numbers) a) +127,     b)-10,     c) -128,     d) +500 B) How would the integer in d) be stored in memory starting ataddress 0A00016? (This problems are from the book: The 8088 and 8086Microprocessors. by Walter A. Triebel and Avtar Singh) Please help me out understanding these problems; I would likeyou to put every operation and explanation possible so I canunderstand these topics (I'll rate lifesavers). 1.- A) Express each of the signed decimal integersthat follow as either a byte- or a word hexadecimal number (use2's-complement notation for negative numbers) a) +127,     b)-10,     c) -128,     d) +500 B) How would the integer in d) be stored in memory starting ataddress 0A00016?

Explanation / Answer

it's hex value will be0x7f

b)-10,    

in 2's complement it willbe
0xF6

c) -128,

hex value0xFF80

    d)+500

hex value 0x1F4

2. Since word is 4 byte,we will divide 500 0x1F4 into 4 bytes.

which will be

0x00
0x00
ox01
0xF4

since 8086 uses little endian,

so it will be storedas
0A000 = 0xF4
0A001 = 0x01
0A002 = 0x00
0A003 = 0x00

since 0A000 is divisibleby 4, it is alligned.
