An error pattern ROM compression method for continuous data

This paper proposes a new error pattern ROM (EP-ROM) compression method for continuous data. The EP-ROM reduces the ROM size by dividing the continuous data into coarse values and their errors and by storing the indices of error patterns instead of the errors. This method significantly reduces the ROM size by exploiting the characteristic that the errors for continuous data possess the same patterns. The experiment results show that the EP-ROM achieves 60/spl sim/77% ROM size reductions for various continuous data.
