Filed:

Nov 3, 2000

Appl. No.:

09/706242

Inventors:

Brian D. Erickson - Soquel CA
Barry Wong - Los Gatos CA
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.

International Classification:

US Classification:

326 40, 326 38, 326 39, 326 41, 326 83

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.

International Classification:

G01J 100

US Classification:

356213

Abstract:

An analyte (e. g. , glucose) is tested in a sample (e. g. , blood or blood-free interstitial fluid) having both the analyte and other constituents (e. g. , protein). The analyte has an absorption peak over a narrow bandwidth at a characteristic wavelength. The other constituents have an absorption over a broad bandwidth. The broad bandwidth includes and is broader than the narrow bandwidth. Radiant energy (e. g. , IR radiation) is directed at the sample. The energy has a source bandwidth including the broad bandwidth. The sample absorbs a portion of the energy. A remainder of the energy is available for analysis. The remainder is analyzed by filtering the remainder into an analyte portion and a reference portion. The analyte portion contains substantially only the narrow bandwidth. The reference portion contains substantially only the broad bandwidth.

International Classification:

US Classification:

455418, 455419, 455420

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.
