1 How would the decimal number 1234 be coded in ASCII and st

1. How would the decimal number 1234 be coded in ASCII and stored in memory Starting at address 0C000H? (Assume that the least significant digit is stored at the addressed memory location.)

2. Find the unknown value for each of the following physical addresses. Assume all numbers are hexadecimal numbers
(a) A000:?= A0123
(b) ?:14DA 235DA
(c) D765:?= DABC0
(d) ?:CD21 = 32D21

show the detailed work please.

Solution

1. According to the ASCII decimal number 1234 be coded and stored in the memory starting at address 0C000H,

it will be coded and stored in the memory as:

address        memory

0C000H         34H

0C001H          33H

0C002H           32H

0C003H           31H

2.

(a) A000x10+???? = A0123

????=0123H

(b) ????x10+14DA = 235DA

????=2210H

(c) D765x10+???? = DABC0

????=3570H

(d) ????x10+CD21=32D21

???? = 2600H
