Abstract

A universal processor-direct bus structure on a specifically partitioned motherboard uses a separate local bus translator card to adapt to a specific local bus protocol and configuration. The processor-direct bus on the motherboard contains a superset of all of the primary signals required to implement any desired local bus structure. The translator card incorporates the connectors and bus translation protocol for a specific local bus structure on a separate card which is connected to the partitioned motherboard through the universal processor-direct bus. Thus, the universal processor-direct bus combined with the translator card makes it possible to have a standard bus (for example an ISA (Industry Standard Architecture) bus, EISA bus, MCA bus, PCI bus, C-bus, S-100 bus and/or other buses) mounted directly on the motherboard with one or more of the same standard buses or a different local bus interfaced to the motherboard through the universal processor-direct bus. This unique combination of a motherboard having a universal processor-direct bus with plug in local bus translator cards provides a unique, low cost, flexible solution to the problem of standard and local bus obsolescence, local bus non-upgradeability and local bus non-flexibility.
