DATA COMPRESSION APPARATUS AND METHOD |
| 摘要 |
A data compression apparatus includes a memory and a processor. The processor extracts a second character string as a matching string from a character string after a first character string in a character string of data before compression that is stored in the memory, the second character string being identical with the first character string, and identifies a length of the matching string, and a relative position indicating how many addresses the first character string precedes the second character string by. The processor extracts a third character string having a length that is less than the relative position from the extracted second character string. The processor encodes a length of the third character string. The processor encodes the relative position. |

1. A data compression apparatus comprising:
a memory; and a processor that:
extracts a second character string as a matching string from a character string after a first character string in a character string of data before compression that is stored in the memory, the second character string being identical with the first character string, and identifies a length of the matching string, and a relative position indicating how many addresses the first character string precedes the second character string by;extracts a third character string having a length that is less than the relative position from the extracted second character string;encodes a length of the third character string; andencodes the relative position. |
