ABSTRACT:
A method for transforming a logic format includes dividing a data segment into a main data segment having a main segment length and a sub data segment having a sub segment length shorter than the main segment length, allotting the main data segment and the sub data segment respectively to a main address and a sub address of a data storage unit, and defining a combination of a data format of a main data area defined by the main segment length and the number of main addresses and of a data format of a sub data area defined by the sub segment length and the number of sub addresses, as a logic format of the data storage unit. A determination is made at an arbitrary time whether the average of the length of all the data stored in the data storage unit is less than a threshold value. The sub segment length is shortened in response to a determination that the average length of all the data stored in the data storage unit is less than a threshold value. A portion of the sub data area thereby freed-up is allotted to the main data area so as to increase the number of the main addresses.
