For the 8bit word 00111001, the check bits stored with it would
be 0111 .Suppose when the word is read from memory ,the check bits
are calculated to be 1101,What is the data word that was read from
memory?
sol:
hamming code D8 D7 D6 D5 C8 D4 D3 D2 C4 D1 C2 C1
12 11 10 9 8 7 6 5 4 3 2 1
0 0 1 1 0 1 0 0 1 1 1 1
0111 o+ 1101 =1010 表bit是錯誤的 故從記憶體讀出的資料字語為 00011001
可以請問高手是怎麼看出來的
我還真的看不懂
謝謝各位
