Patent ID: 6982662

Claim:
A method for conversion of signals, comprising: receiving a first plurality of bits from a signal; performing a look-up in a table with a first subset of bits in the first plurality of bits to generate a result; adding the result to generate a sum; performing another look-up in the table with a second subset of bits in the first plurality of bits and adding the result to the sum until a look-up with a last subset of bits in the first plurality of bits is performed and the result added to the sum, wherein the table is a two dimensional array containing a plurality of elements, the size of the first dimension equal a number of bits in the plurality of bits divided by a number of bits in the subset of the plurality of bits, the size of the second dimension equal to 2 (numbers of bits in subset) ; outputting the sum as a first multiple bit value; and receiving a second plurality of bits from the signal and converting to a second multiple bit value using the steps described above until all bits in the signal have been converted, wherein each plurality of bits has the same number of bits and each subset of bits in the plurality of bits has the same number of bits.
