ABSTRACT:
A programmable logic device has a plurality of levels of programmable logic modules with fixed interconnections. The outputs of a level connect to inputs of the next level of programmable logic modules. The first level is fed from a bank of memory elements and the inputs to this bank of memory elements are derived from the last level. Crossbar switches are optionally inserted between a carefully chosen pairs of levels.
