Abstract: A circuit for translating a configuration file used to configure a programmable logic device includes a first register to serially receive configuration data. A second register receives, in parallel, configuration data from the first register. A translation address memory translates an original address for a selected configuration bit of the configuration data to a translated address. A translation memory stores the selected configuration bit at the translated address. Control logic selectively downloads configuration data from the translation memory to a programmable logic device core.

Abstract: A technique for configuring programmable integrated circuits. The technique involves preconditioning or predefining the outputs and I/Os of a programmable integrated circuit before the device is programmed or reconfigured. When the device is programmed, the outputs and I/Os of the programmable integrated circuit will be driven to the preconditioned or predefined states. The technique may be implemented in conformance with the IEEE 1149.1 boundary scan architecture standard. Standard IEEE 1149.1 instructions may be used. The technique may also be used during in-system programming of programmable integrated circuits.

Abstract: Fragrance releasing crystal beads are provided which gradually release a fragrance under anhydrous conditions and provide a rapid release of fragrance when wetted. The beads comprise a water-soluble particulate carrier, e.g. prilled urea, coated with a finely divided highly absorptive inorganic matrix containing the fragrance. The beads optionally include emollients and bacteriostats and the like and can be used for pleasingly perfumed sachets or as bath beads or as agents for the control of malodors in pet litter. The particulate beads may be conspicuously colored such that their color substantially disappears as they are dissolved, giving a visual indication of the need for replenishment.
