摘要： A circuit and corresponding method for providing a reference voltage are presented. The circuit includes a current source having a magnitude with positive temperature correlation connected to a node, and a diode element connected between the node and ground, where the node supplies the reference voltage. The circuit also includes a variable resistance connected to receive an input indicative of the circuit temperature and through which the diode element is connected to the node. The value of the variable resistance is adjusted based upon the circuit temperature input. The circuit is useful for application as a peripheral circuitry, such as on a flash or other non-volatile memory and other circuits requiring an on-chip reference voltage source.

摘要： A method for modifying a compiled integrated circuit floorplan is provided. A non-optimally placed functional element within the floorplan is identified and then moved to a tray region outside of the integrated circuit floorplan. A location to move the non-optimally placed functional element is identified. In one embodiment, the location to move the non-optimally placed functional element is not viewable in the same display as the original location of the non-optimally placed functional element. The non-optimally placed functional element is then relocated from the tray region to a new location within the floorplan. The modified floorplan may be recompiled upon relocation of the functional element. A computer readable medium, a graphical user interface, and a system for designing an integrated circuit are also provided.

摘要： A multi-port adapter and method of operation suitable for use with serial ATA devices is disclosed. An adapter includes a switch that receives input from multiple host devices and an arbiter module for assigning a priority scheme to received commands. An outstanding request table is implemented as a memory module for storing identifying information associated with commands received from multiple host devices, and a free pointers queue is maintained to track slots available in the outstanding request table. A command tracker state machine decodes incoming requests from hosts, monitors the execution by these commands by the ATA device, and updates the memory module to reflect completion of commands. Also disclosed is a storage system including an adapter of the present invention and ATA storage devices.

摘要： As a program is replaced by the operating system running within a microprocessor, only those entries associated with the replaced program and resident within effective-to-real address translation units will be replaced. Those entries within the effective-to-real address translation units associated with the operating system and shared libraries, and any other software units operating within the microprocessor will not be invalidated.

摘要： A method of compositing a plurality of graphic objects with a compositing buffer, is disclosed. The plurality of graphic objects forming a group is attenuated by group opacity and is composited from a top object to a bottom object. Based on a first mask and the group opacity, a second mask is generated. The first mask stores a remaining possible contribution for further graphic objects below and including the plurality of graphic objects. The plurality of graphic objects in a top down order is processed. In particular, for each graphic object of the plurality of graphic objects: (a) a contribution value for the graphic object using the second mask is determined, the contribution value representing a contribution of the graphic object to the compositing buffer; (b) a colour value of the graphic object is composited with the compositing buffer using the contribution value; and (c) the second mask is updated using the contribution value. The first mask is then updated using the second mask and the group opacity. The updated first mask is configured for further compositing of objects below the plurality of graphic objects.

摘要： A method for validating timing violations in a testbench is provided. The method includes obtaining the timing requirements for a design under test from a first file. The timing requirements for the design may be entered as an input to a verification tool. Then, based on the timing requirements of the user, a place and route operation is performed resulting in a design layout. Following the place and route operation, timing results are obtained for the design layout. The timing results may be obtained through simulation. From the timing results, timing values are extracted at the input level so that the inputs may be driven based on those timing values. The timing values compensate for any timing violations that may have resulted from the timing models of the verification tool.
