Abstract
um dispositivo de memória inclui uma tabela de cores comprimida tendo uma tabela de diferenças comprimida e uma tabela de resíduos. a tabela de diferenças inclui nós de diferenças em que cada nó de diferença representa um valor que é uma diferença entre um valor de um nó de uma tabela de cores original e um valor de um nó correspondente de uma tabela de cores de referência. a tabela de resíduos inclui nós de resíduos em que cada nó de resíduo representa um valor que é uma diferença entre um valor de um nó da tabela de cores original e um valor de um nó correspondente de uma tabela de diferenças comprimida reconstruída.
