| 发明名称 | 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. | ||

| 主权项 | 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. | ||
