Appl. No.:

09/706242

Patrick T. Bever - Santa Clara CA

Assignee:

Xilinx, Inc. - San Jose CA

International Classification:

G11C 700

US Classification:

36518907, 36518901, 36523008

Abstract:

A programmable logic device (PLD) including a non-volatile memory array for persistently storing configuration data, and a volatile memory array for temporarily storing the configuration data and controlling the various logic resources of the PLD to perform a users logic operation. When the PLD is reset, an addressing circuit causes a column of non-volatile memory cells to transmit configuration data values to a corresponding column of volatile memory cells on a series of write lines. To verify that a configuration data value is successfully written from each non-volatile memory cell to a corresponding volatile memory cell, the data value transmitted on each write line is compared with the stored data value transmitted from each volatile memory cell on a corresponding read line. A control signal is generated when all of the data values transmitted on the write lines are equal to stored data values transmitted on corresponding read lines, thereby indicating that the configuration data values are successfully transferred to the column of volatile memory cells. The control signal is used to increment the address circuit, thereby addressing a next sequential column of non-volatile memory cells and associated volatile memory cells.

Abstract:

A power control output circuit for a PLD that allows the PLD to selectively operate in either a low current (ânormalâ) output mode, or a high current power control mode. In one embodiment, the power control output circuit is incorporated into a special Input/Output Blocks (PC-IOB) of the PLD. When no power control function is needed, a high current output portion of the power control output circuit is deactivated by storing an associated data value a power control configuration memory cell of the PLD, and an output driver of the PC-IOB generates low current output signals on a device I/O terminal. To perform power control functions, a portion of the PLDs programmable logic circuitry is configured to generate a power control data signal, and the high current output portion of the power control output circuit is enabled by storing a corresponding data value in the power control configuration memory cell. When the power control data signal is generated while in the high current power control mode, the high current output circuit turns on a high current transistor that generates a high current power control output signal at the device I/O terminal.

Abstract:

A wireless programmable logic device contains a wireless component and a programmable logic component. A remote wireless host can be used to program the programmable logic device. Some product designs require multiple programmable logic devices. When wireless programmable logic devices are used in the design, all of them can receive data and commands from the host. As a result, the wireless host can control the order of configuration and the start time of these logic devices. There is no need to build glue logic for this purpose. Consequently, the efficiency in product design is improved. If there are problems in programming a programmable logic device, the host can log the failed operation in its memory. This information could be used to improve production flow.

Abstract:

Method and system for a programmable device programmer. The disclosure describes various embodiments for programming a target programmable device by a programmer. In one embodiment, the programmer determines availability of updated configuration data for a hardware component of the programmer. The programmer includes the software component coupled to the hardware component. An update mode of the hardware component is enabled in response to availability of the updated configuration data, and programming of the target programmable device is disabled while the hardware component is in the update mode. A programmable device internal to the hardware component is programmed with the updated configuration data while the hardware component is in the update mode, and the update mode is disabled in response to completion of programming of the at least one programmable device. A target programmable device may then be programmed by the programmer having the updated configuration data.

Abstract:

A template-based supervisory process control and manufacturing information application development facility is disclosed that includes a number of time-saving application development tools that significantly enhance design productivity and allow re-using of previously developed application building blocks. The development facility includes an application object template library that stores a set of previously defined application object templates. The template library is accessed by developers through a configuration utility that facilitates specifying instances of the set of previously defined application object templates to be included in an application. Thereafter, application objects are instantiated from the selected ones of the set of previously defined application object templates in a build of the specified application.

Abstract:

A multi-tiered replicated process database and corresponding method are disclosed for supporting replication between tiers. The multi-tiered replicated process database comprises a tier one (T1) database server computer including a process history database and a replication service. The replication service includes a set of accumulators. Each accumulator is adapted to render a summary T2 database tag data structure from a set of data values retrieved from the process history database for a specified T1 database tag. The replicated database system also includes a tier two (T2) database server computer comprising a consolidated database that includes process data replicated from a set of T1 database servers. At least a portion of the process data replicated from the set of T1 database servers is summary T2 database tag data rendered by the set of accumulators.
