A PROGRAMMABLE INTERCONNECT NETWORK FOR LOGIC ARRAY

摘要

The present invention provides a programmable interconnect network for an array of logic cells. Said interconnect network comprises a plurality of switch boxes being connected in a tree structure and providing connections to its logic cells, switch boxes located at the lowest level of the tree structure are connected to logic cells; said interconnect network also comprises peripheral switch boxes, of which at least one is connected to an external logic. An integrated circuit comprising an FP array of logic cells connected by the said programmable interconnect network and a mask programmable (MP) logic array are also disclosed.
