Abstract

Patente de Invenção:<B>"MICROCOMPUTADOR"<D>. Em um microcomputador, no qual roda uma série de programas de usuário, através de uma MMU assegura-se que por meio de nenhum programa de usuário se possa ter acesso a outros programas. No entanto, para se poder aproveitar programas de biblioteca em comum e ao mesmo tempo para se impedir um salto descontrolado para estes é prevista uma zona de memoria de vetor, na qual os endereços iniciais dos programas de biblioteca acham-se registrados como objetivos de salto (vetores: 1050, 3000). Uma solicitação de um programa de biblioteca é efetuada através de fornecimento do número de vetor (0 ... n), a partir do qual MMU determina o endereço correspondente na zona de memória de vetor.
