Patent number: 9515880Abstract: An integrated circuit device may include processing circuits that can be dynamically reconfigured to perform different tasks each of which utilizes different system clock resources. The device may include clock selection circuitry that can selectively route desired clock signals to corresponding processing circuits. The clock signal provided to each processing circuit may be selected based on a current configuration of that processing circuit. Client processing circuits in a network switch may be coupled to interchangeable client networks. The client processing circuits may be dynamically reconfigured based on characteristics of the client networks that are currently coupled to the network switch. By dynamically selecting which clock resources are provided to the processing circuits, clock resources such as global clock signals that are relatively scarce may be reserved for processing circuits that can only function with the relatively scarce clock resources.Type: GrantFiled: December 28, 2011Date of Patent: December 6, 2016Assignee: Altera CorporationInventors: Ramanand Venkata, Henry Y. Lui, Victor Maruri, David W. Mendel, Andrew Bellis

Patent number: 8581653Abstract: An integrated circuit includes a local clock network that is operable to provide a first clock signal and an interface circuit that is coupled to receive the first clock signal from the local clock network. The interface circuit is operable to generate a second clock signal based on the first clock signal. A clock line is coupled to the interface circuit. The clock line has a fixed length. The second clock signal is provided to a multiplexer circuit through the clock line. The multiplexer circuit provides a third clock signal based on the second clock signal. Another clock network is coupled to receive the third clock signal from the multiplexer circuit.Type: GrantFiled: December 16, 2011Date of Patent: November 12, 2013Assignee: Altera CorporationInventors: Victor Maruri, Arch Zaliznyak, Ramanand Venkata, Henry Y.

Patent number: 7839167Abstract: A programmable logic integrated circuit device has a plurality of regions of programmable logic disposed on the device in a plurality of intersecting rows and columns of such regions. Interconnection resources (e.g., interconnection conductors, signal buffers/drivers, programmable connectors, etc.) are provided on the device for making programmable interconnections to, from, and/or between the regions. At least some of these interconnection resources are provided in two forms that are architecturally similar (e.g., with similar and substantially parallel routing) but that have significantly different signal propagation speed characteristics. For example, a major or larger portion of such dual-form interconnection resources may have what may be termed normal signal speed, while a smaller minor portion may have significantly faster signal speed. Secondary (e.g.Type: GrantFiled: January 20, 2009Date of Patent: November 23, 2010Assignee: Altera CorporationInventors: Tony Ngai, Bruce Pedersen, Sergey Shumarayev, James Schleicher, Wei-Jen Huang, Michael Hutton, Victor Maruri, Rakesh Patel, Peter J.

Patent number: 7262635Abstract: 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.Type: GrantFiled: September 1, 2006Date of Patent: August 28, 2007Assignee: Altera CorporationInventors: James Schleicher, Jim Park, Sergey Shumarayev, Bruce Pedersen, Tony Ngai, Wei-Jen Huang, Victor Maruri, Rakesh Patel
