Abstract
The invention in the simplest form is a programmable logic device consisting of gate arrays, external I/O endpoints, and an embedded switch fabric configurable for connecting gates to gates, endpoints to endpoints and gates to endpoints. The architecture may employ a fabric interface of non-blocking crossbar switches for making complex bus connections of multiple devices to facilitate high speed processing.
Claims19
A programmable logic device, comprising:
- an integrated circuit having therein a plurality of logic blocks configured substantially in a plane;
- a plurality of end points internal to the integrated circuit, each of the end points being at least connectible to one of the logic blocks;
- and
- a switched fabric embedded within the integrated circuit and offset from the plane of the logic blocks so as to traverse at least some of the logic blocks, the switched fabric providing non-contentious interconnection between at least some of the end points.

A programmable logic device, comprising:
- an integrated circuit having therein at least one reconfigurable gate array arranged substantially in a plane;
- at least one I/O point;
- and
- a configurable switched fabric embedded within the integrated circuit, the switched fabric having a plurality of endpoints at least connectible to a plurality of locations within the reconfigurable gate array, and at least one of the endpoints being at least connectable to the at least one I/O point, the switched fabric being offset from the plane of the gate array so as to traverse at least a portion of the gate array.
