Patent number: 8598907Abstract: Some embodiments provide an IC with configuration context switchers. The IC includes several configurable circuits, each of which configurably performs one of several operations at any given time, based on the configuration data set that it receives at that time. The IC includes several storage circuits for storing several configuration data sets for each of the configurable circuits. The IC also includes a context switching interconnect circuit for switchably connecting the configurable circuit to different sets of storage circuits to receive different sets of configuration data sets. The context switcher includes one or more stages for re-timing the data coming from the configuration storage elements. The stages can include interconnect circuitry or storage circuitry. Some embodiments build one of the stages in the configuration data storage elements. Some embodiments encode the configuration data bits and hence utilize a decoder in the context switcher to decode the encoded configuration data.Type: GrantFiled: January 27, 2012Date of Patent: December 3, 2013Assignee: Tabula, Inc.Inventors: Trevis Chandler, Joe Entjer, Martin Voogel, Jason Redgrave

Patent number: 8456190Abstract: An integrated circuit (“IC”) that includes a configurable routing fabric with controllable storage elements is described. The routing fabric provides a communication pathway that routes signals to and from source and destination components. The routing fabric may provide the ability to selectively store the signals passing through the routing fabric within the storage elements of the routing fabric. In this manner, a source or destination component may continually perform operations (e.g., computational or routing) irrespective of whether a previous signal from or to such a component is stored within the routing fabric. The source and destination components include configurable logic circuits, configurable interconnect circuits, and various other circuits that receive or distribute signals throughout the IC.Type: GrantFiled: March 16, 2011Date of Patent: June 4, 2013Assignee: Tabula, Inc.Inventors: Jason Redgrave, Martin Voogel, Steven Teig

Publication number: 20130093461Abstract: An integrated circuit (“IC”) having configurable logic circuits for configurably performing multiple different logic operations based on configuration data is provided. The IC includes a configurable routing fabric for configurably routing signals among configurable logic circuits. The configurable routing fabric includes a particular wiring path that connects an output of a source circuit to inputs of a destination circuit. The particular wiring path includes a first path and a second path that is parallel to the first path. The first and second paths are for configurably storing output signals of the source circuit. The first path connects to a first input of the destination circuit and the second path connects to a second input of the destination path.Type: ApplicationFiled: July 2, 2012Publication date: April 18, 2013Inventors: Martin Voogel, Steven Teig, Trevis Chandler

Publication number: 20130093462Abstract: A low power sub-cycle reconfigurable conduit is provided. The low power reconfigurable conduit is a clocked storage element that consumes less power when performing low-throughput operations that do not require sub-cycle rate. The low power conduit includes a first configurable routing multiplexer that is reconfigurable to select one of several inputs at a first clock rate. The low power conduit also includes an array of storage elements for storing output data from the configurable routing multiplexer at the first clock rate. Each storage element in the array of storage elements operate at a second clock rate that is slower than the first clock rate. Each storage element receives a different phase of a clock that operates at the second clock rate. The low power conduit also includes a second configurable routing multiplexer that is reconfigurable to select from the array of storage elements at the first clock rate.Type: ApplicationFiled: July 13, 2012Publication date: April 18, 2013Inventors: Steven Teig, Christopher D.
