Bi-directional buffers for mounting a plurality of integrated circuit devices

摘要

A field programmable logic module provides a set of sockets for mounting electronic components, a set of connector pins for providing external access to the board, and a set of field programmable interconnect devices (FPIDs). The FPIDs are buffered, multiple port cross-point switches that may be programmed by a host computer to selectively connect terminals of the components mounted in the sockets to one another or to the external connector pins. Signal buffers within the FPID ports can be programmed to provide various types of buffering and logic operations on the signals routed by the FPIDs.
