Abstract:
PROBLEM TO BE SOLVED: To provide interconnection resources applied to programmable logic devices for accelerating an operating speed of a programmable logic array integrated circuit device.SOLUTION: A programmable logic integrated circuit (10) has a plurality of programmable logic regions (20) disposed on a device in an array of intersecting rows and columns of the plurality of regions. Interconnection resources (e.g., interconnection conductors or the like) are provided for forming programmable interconnections region to region and/or between the regions. At least some of these interconnection resources are configured in two forms having architecturally similar but significantly different signal transmission speed characteristics. For example, a major or larger portions (200a, 210a, 230a) of the dual-form interconnection resources have what is termed a normal speed, and smaller portions (200b, 210b, 230b) have a significantly faster signal speed.
Abstract:
A programmable logic device has many regions of programmable logic, together with relatively general-purpose, programmable, interconnection resources that can be used to make interconnections between virtually any of the logic regions. In addition, various types of more local interconnection resources are associated with each logic region for facilitating the making of interconnections between adjacent or nearby logic regions without the need to use the general-purpose interconnection resources for those interconnections. The local interconnection resources support flexible clustering of logic regions via relatively direct and therefore high-speed interconnections, preferably in both horizontal and vertical directions in the typically two-dimensional array of logic regions. The logic region clustering options provided by the local interconnection resources are preferably boundary-less or substantially boundary-less within the array of logic regions.

PROBLEM TO BE SOLVED: To provide interconnection resources to be applied to a programmable logic device for accelerating an operating speed of a programmable logic array integrated circuit. SOLUTION: A programmable logic integrated circuit device (10) has a plurality of regions (20) of programmable logic disposed on the device in a plurality of intersecting rows and columns of such regions. Interconnection resources (e.g., interconnection conductors) are provided for making programmable interconnection to, from and/or between the regions. At least some of these interconnection resources are provided in two forms that are architecturally similar but that have significantly different signal propagation speed characteristics. For example, a major or larger portion of such dual-form interconnection resources (200a, 210a, 230a) may have what may be termed normal signal speed, while a smaller minor portion (200b, 210b, 230b) may have significantly faster signal speed.

Abstract:
PROBLEM TO BE SOLVED: To provide a standard cell element of which layout, wiring connection, manufacture and input/output connection architecture can be simplified in a programmable logic device, in which an increasing die size and a packaging density makes a signal path longer and finer, and as a result, presenting the problem of signal delay and signal skew. SOLUTION: A unified cell 80 comprises a cell 86 of a logic array block, a hexagonal interface bump 82 of which size can be easily changed, a trace 88 for electrically connecting a signal drive from an input/output band 84 to a bump 82, a separated power bus 90. The input/output band 84 is aligned with the input/output band 84 of a neighboring unified cell. This eliminates the need for a conventional connection circuit.

Interconnection resources for making programmable interconnections to, from and/or between the regions (e.g., interconnecting conductors or the like) are provided on the device. At least some of these interconnection resources are constituted of two forms, that are architecturally similar but that have markedly different signal propagation speed characteristics. For example, a major or larger portion of such dual-form interconnection resources (200a, 210a, 230a) may have what is called a "normal signal speed", while the smaller of the portions (200b, 210b, 230b) has a significantly higher signal speed.
