Abstract

Un sistema de varios procesadores (100) para compartir memoria compuesto por una memoria (102) y dos o más procesadores (104). Los procesadores están programados para definir (202) agrupaciones de memorias intermedias entre los distintos procesadores, y para cada agrupacion de memorias intermedias, definir (204) un conjunto de punteros de memorias intermedias que apuntan a las memorias intermedias correspondientes. Además, los procesadores también están programados para definir (206), para cada conjunto de punteros de memorias intermedias, un puntero de consumo para el procesador que posee la agrupacion de memorias intermedias, y un puntero de liberacion para el otro procesador que comparte dicha agrupacion de memorias intermedias en la que cada puntero senala inicialmente a una ubicacion predeterminada del conjunto y para ajustar (208-236) los punteros de consumo y de liberacion de acuerdo con las memorias consumidas y liberadas.
