SYSTEM AND METHOD FOR EXPANSION OF A COMPUTER

摘要

A system and method for interfacing at feast one ISA and/or PCI compliant device with a PCM- CIA compliant-device socket (124) on a host com- puter (I22) 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.
