Abstract

This paper proposes a new error pattern ROM (EP-ROM) compression method for continuousdata. 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 non. 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∼77% ROM size reductions for various continuous data.

본 논문에서는 연속적인 데이터를 위한 새로운 에러패턴 ROM(error pattern ROM: EP-ROM) 압축 기법이 제한되었다. EP-ROM은 연속적인 데이터를 근사값과 에러로 나눈 후 에러 대신 에러패턴의 인덱스를 저장함으로써 ROM의 크기를 줄인다. 이 기법은 연속된 데이터를 양자화할 때의 많은 경우 같은 에러패턴을 가진다는 특징을 이용한 것으로 ROM의 크기를 매우 작게 줄일 수 있다. 실험결과에서는 EP-ROM은 다양한 연속적인 데이터에 대하여 ROM 크기를 60∼77% 줄였다.
