Fast logic sharing is created using a feedback path from the output logic macrocell of one functional block to the product term inputs of another function block without going through an advanced interconnect matrix (AIM). The fast feedback path may be provided from the macrocell after the product terms XOR gate without registering, and / or after the register in the macrocell. The fast logic sharing avoids the slow AIM for feedback logic, and allows additional resources to be borrowed from other function blocks with a limited delay penalty. In particular, delay penalties resulting from dividing wide operations requiring multiple product terms between the product terms of multiple functional blocks are significantly reduced.

Methods and systems are described for computing page rankings more efficiently. Using an interconnectivity matrix describing the interconnection of web pages, a new matrix is computed.

The data structure storing the interconnectivity information is preferably also physically sorted according to the eigenvector. By reorganizing the matrix used in the web page ranking computations, caching is performed more efficiently, resulting in faster page ranking techniques. Methods for efficiently allocating the distribution of resources are also described.

A dielectric wiring structure and method of manufacture therefor. Successively formed wiring layers synergistically combine with subsequently formed sidewall supports spanning two or more layers to form a self supporting air dielectric interconnection matrix. Wires are supported by vertical nitride sidewalls which are, in turn, held in place and supported by the wires. After forming the complete wiring-sidewall structure, SiO2 between and under the wires is removed using gaseous HF at a partial pressure between 5 and 30 Torr. The metal wires may be clad with nitride for short and oxidation protection. Because sidewalls are formed after wiring, with the wiring at each level providing support definition, complex support alignment is unnecessary.
