Abstract

resumo método de configuração de um processador, dispositivo para configuração de um processador, processador, e produto de programa de computador o uso não autorizado de programas de computador é dificultado compilando um processador ao invés de somente compilar um programa em código de máquina. a maneira na qual o processador deve responder às instruções da máquina, isto é, seus dados de decodificação, é computada de uma sequência de bits b arbitrária e um programa p como inserções. os dados de decodificação de um processador são computados, os quais executarão operações definidas pelo programa p quando o processador usa a dada sequência de bits b como uma fonte de instruções da máquina. um processador é configurado de forma a executar as instruções de máquina de acordo com os ditos dados de decodificação. outros programas p’ podem então ser compilados em instruções de máquina b’ para aquele processador e executada pelo processador. sem conhecer a sequência de bits b e o programa original p, é difícil modificar as instruções da máquina b' de forma que um processador diferente executará o outro programa p’. 1/1
