A structured logic array is divided into hierarchical levels. At a highest level (the chip level), blocks are interconnected by a system of chip busses. A block interface couples each block to the chip bus system to allow the blocks to communicate with each other. At a lower level, each block includes sectors, each sector being coupled to a block bus system by a sector interface. The block bus system interconnects the sectors in each block to allow the sectors to communicate with each other. The block bus system is also coupled to the block interface to allow signals to be transferred between the block bus system and the chip bus system. At a lowest level, each sector includes a plurality of logic elements. The logic elements are interconnected by a sector bus system. The sector bus system is coupled to the sector interface to allow for the transfer of signals between the sector bus system and the block bus system.
A hierarchically-structured programmable logic array, comprising: a plurality of sectors, each sector comprising: a plurality of logic cells; and a sector bus system for interconnecting said logic cells within said sector; a block bus system disposed externally to said sectors; and an interface for
A hierarchically-structured programmable logic array, comprising: a plurality of sectors, each sector comprising: a plurality of logic cells; and a sector bus system for interconnecting said logic cells within said sector; a block bus system disposed externally to said sectors; and an interface for selectively coupling the plurality of sector bus systems to said block bus system, said interface having a K number of lower level ports coupled to said sector bus systems, and an N number of higher level ports coupled to said block bus system, where N is less than K.
