Abstract:
1. A method for data transferring in a circuit using looking up table, the method comprising: creating, at a processor of the circuit, a main table function having a main table, wherein the size of the main table is determined by a predetermined value, and querying the main table obtains the result of the main table function; creating, at the processor of the circuit, a fixed table function having a fixed table, wherein the fixed table function is determined by the quantity of a plurality of modifiers, and the size of the fixed table is determined by the size of the main table and the predetermined value; creating, at the processor of the circuit, a rest table function having a rest table, wherein the size of the rest table is determined by the operation range of the data transferring, the size of the main table, and the predetermined value; obtaining, at the processor of the circuit, the result of data transferring by selecting a function among the main table function, the fixed table function, and the rest table function, and performing a process of looking up table on one of the main table, the fixed table, and the rest table corresponding to the selected function based on the size of data to be transferred; and wherein the data transferring is: Q(x)=x that is d≦X max .
