Abstract: A method of loading data into register files that correspond to respective execution units within a data-parallel processor. After receiving a first set of parameters that specify a subset of data within a first memory, the first set of parameters are compared to a plurality of sets of conditions that correspond to respective patterns of data. The first set of parameters is then converted to a second set of parameters in accordance with one of the sets of conditions satisfied by the first set of parameters. A sequence of memory addresses are generated based on the second set of parameters. Data is retrieved from locations within the first memory specified by the sequence of memory addresses and loaded into register files that correspond to respective execution units within a processor.

Abstract: A system for multiple task management between processors includes a first processing device for executing tasks. A respective storage element is provided for storing one or more commands from each of the tasks. A command dispatcher is provided for selectively transferring a command from one of the storage elements to a command queue provided within a second processing device.

Abstract: Within a data processing system, a user-entered data declaration within a program source file is inspected to determine whether a first qualifier is provided with or omitted from the user-entered data declaration. If the first qualifier is provided, an unreserved data storage location disposed within a data-processing integrated-circuit (IC) device is identified and allocated for storage of data associated with the user-entered data declaration.

Abstract: A method is described herein for designing a circuit using graphic editor software. A graphic design file is generated corresponding to a block diagram created in a graphical user interface associated with the graphic editor software. The block diagram includes a plurality of blocks and a plurality of conduits interconnecting the blocks. A block design file is generated in one of a plurality of formats for each of selected ones of the plurality of blocks in the block diagram. Each of the block design files corresponds to an implementation of its corresponding block. Modifications to any of the graphic design file and the block design files are incorporated into each other under software control.

Abstract: An apparatus and method for in-system programming of programmable devices includes a device configuration program with adaptive programming source code instructions that characterize device configuration instructions and data. The adaptive source code instructions may include conditional branches, subroutines, variables, configurable arrays, integer operators, and Boolean operators. These features allow for more compact and efficient device configuration instructions and data. An interpreter converts the device configuration program into formatted device configuration instructions and data. The formatted device configuration instructions and data are preferably compatible with IEEE 1149.1 JTAG-BST specifications. The formatted device configuration instructions and data are used to program a programmable device in the manner specified by the adaptive programming source code instructions.

Abstract: A method for simulating a portion of a circuit design is described. The circuit design includes a plurality of design files each corresponding to one of a plurality of design entities in the circuit design. A subset of the design entities is selected. The subset of the design entities corresponds to the portion of the circuit design to be simulated. In response to selection of the subset of the design entities, a netlist is generated under software control directly from the design files associated with the subset of the design entities. The portion of the circuit design is then simulated using the netlist.

Abstract: A method for upgrading software is described. According to the invention, in response to operation of the software on a first platform, a connection is established between the first platform and a remote platform. Where first version data associated with the software are different from second version data from the remote platform, a portion of the software is overwritten with first updated code from the remote platform.

Abstract: A method for designing a circuit is described. A block diagram corresponding to the circuit is generated according to an external specification associated with the circuit. Each block in the block diagram has a block specification associated therewith. A design file is generated for each block in the block diagram using the associated block specification and one of a plurality of design file templates. Each block in the block diagram is implemented by editing its corresponding design file. The operation of each block in the block diagram is simulated. A overall design for the circuit is compiled. After the design is compiled, changes are incorporated into the compiled design in response to changes in at least one design file through the use of software links maintained between the compiled design and the design files. A device is then configured according to the compiled design.

Abstract: A method is described herein for generating a design file corresponding to a design entity in a logic design. An input and an output are specified for the design entity. A design file type is specified. The design file is created and a design file template corresponding to the design file type is copied into the design file. The design file template includes formatting corresponding to the design file type. The input and the output are instantiated in the design file. The designer may then completely specify the design entity in the design file.
