A system and method for interfacing at least one ISA and/or PCI compliant device with a PCM- CIA compliant device socket (124) on a host com- puter (122) is disclosed. Preferably included in the system are structures to carry out the functions of: interrupt translation between the PCMCIA port and the ISA devices; direct memory access translation between the PCMCIA port and the ISA devices; translation of bus address latch enable signal be- tween the PCMCIA port and the ISA devices; trans- lation between memory read and memory write sig- nal of the PCMCIA port and a system memory read signal and a system memory write signal of the ISA devices: translation between the PCMCIA port and 8 bit ISA devices; providing a clock signal to the ISA devices; supplying power to the ISA devices; and translation of the timing between the PCMCIA port and the ISA devices.
L'invention concerne un système et un procédé permettant d'établir une interface entre au moins un dispositif conforme à la norme Industry Standard Architecture (ISA) et/ou la norme Peripheral Component Interconnect (PCI), d'une part, et une prise de dispositif (124) conforme aux normes (PCMCIA) sur un ordinateur central (122), d'autre part. De préférence, le système comporte des structures qui permettent d'assurer les fonctions suivantes: interruption de la translation entre le port PCMCIA et les dispositifs ISA; translation d'accès direct à la mémoire entre le port PCMCIA et les dispositifs ISA; translation du signal de validation de verrouillage d'adresse de bus entre le port PCMCIA et les dispositifs ISA; translation entre les signaux de lecture et d'écriture en mémoire du port PCMCIA et les signaux de lecture et d'écriture dans la mémoire du système propres aux dispositifs ISA; translation entre le port PCMCIA et les dispositifs ISA à 8 bits; transmission d'un signal d'horloge aux dispositifs ISA; alimentation en énergie des dispositifs ISA et translation de la synchronisation entre le port PCMCIA et les dispositifs ISA.
