Abstract

A module for supporting and connecting programmable logic devices through a common interface. A card in the PC Card format is provided with bus interface support for interconnection to other such modules. The module supports one or more programmable logic devices, each of which is connectable to four connectors, two each on top of the module, two each on the bottom of the module. Each connector includes a plurality of pins for electrical signals. These signals include one or more progammable buses, structured to form an expansible system. In a preferred embodiment, the buses include multiple, distinct, programmable buses.
