Abstract (en)
[origin: WO2006076276A2] A programmable logic structure is disclosed that has a set of dedicated lines which extends internally throughout different dedicated logic cells within a logic and routing block (LRB), extends from a previous logic routing block to the present logic and routing block, or extends from the present logic and routing block to the next logic and routing block. In addition, a programmable logic structure employs input logic routing cell (ELRC) multiplexers and output logic routing cell (OLRC) multiplexers for making local connections between dedicated logic cells. Furthermore, a dedicated logic cell in a programmable logic structure is constructed with the following primary components: a configurable logic function or look-up table (LL), a dedicated logic function (DL), a sequential logic function (LS), and a control logic function (LC).
