ABSTRACT:
The invention in the simplest form is a programmable logic device comprising logic blocks configured substantially in a plane, external I/O endpoints, and embedded switched fabrics which provide non-contentious connection between the logic blocks and between logic blocks and I/O endpoints, the switch fabrics being offset from the plane of the logic blocks. The logic blocks are organized into logic groups, whereby a plurality of primary embedded switch fabrics are configurable for connecting logic blocks within logic groups, and at least one secondary switch fabric provides non-contentious connection between primary switch fabrics. The switch fabrics can employ non-blocking crossbar switches. A hierarchy of secondary switch fabrics can be included for providing non-contentions connection between both primary and other secondary switch fabrics.
