Abstract: A programmable logic device includes configurable phase-locked loop (PLL) circuitry that outputs multiple clock signals having programmable phases and frequencies. Each output signal is programmably selectable for use as an external clock, internal global clock, internal local clock, or combinations thereof. The PLL circuitry has programmable frequency dividing, including programmable cascaded frequency dividing, and programmable output signal multiplexing that provide a high degree of clock design flexibility.

Abstract: Systems and methods for packaging integrated circuit chips in castellation wafer level packaging are provided. The active circuit areas of the chips are coupled to castellation blocks and, depending on the embodiment, input/output pads. The castellation blocks and input/output pads are encapsulated and held in place by an encapsulant. When the devices are being fabricated, the castellation blocks and input/output pads are sawed through. If necessary, the wafer portion on which the devices are fabricated may be thinned. The packages may be used as a leadless chip carrier package or may be stacked on top of one another. When stacked, the respective contacts of the packages are preferably coupled. Data may be written to, and received from, packaged chips when a chip is activated. Chips may be activated by applying the appropriate signal or signals to the appropriate contact or contacts.

Abstract: A programmable logic device includes high-speed serial interface (“HSSI”) circuitry that employs one or more clock signals. In addition to use of these clock signals in the HSSI circuitry, circuitry is provided for allowing at least one of these signals to be distributed throughout the PLD core circuitry, e.g., for use as an additional clock signal in the PLD core. Clock distribution is preferably done in a low-skew way.

Abstract: Systems and methods for providing distributed configuration storage are presented. The configuration storage is divided into distributed configuration target modules that are physically located in each design section of a device that uses configuration storage. A distributed configuration master module, physically located near the host interface, controls access into and out of each target module via a distributed configuration bus. The creation of each storage array in the distributed configuration storage can be automated using a scripting tool that converts each register specification into hardware description language code.

Abstract: Measure-controlled delay (MCD) circuits include a measure circuit and sample circuit for synchronizing an output clock to an input clock. In response to triggering of the measure circuit, sample circuits sample outputs of a measure delay array. Sample reset logic prevents output of the output clock when any of a predetermined one or more of the samples correspond to a particular logic value (i.e., logic “1” or “0”). For example, sample reset logic may prevent an MCD circuit from providing the output clock when a sample taken from the earliest sampling point of the measure delay array corresponds to logic “1.” The MCD circuit may then provide the output clock in response to a subsequent triggering for which a sample taken from the earliest sampling point is logic “0.” Phase error of the output clock is thereby reduced. MCD circuits improve response to process, voltage and temperature (PVT) variations.

Abstract: Circuitry for distributing clock signals (e.g., reference clock signals) among a plurality of blocks of circuitry. Each block may include reference clock source circuitry and reference clock utilization circuitry. Each block also preferably includes an identical or substantially identical module of clock signal distribution circuitry that can (1) accept a signal from the source circuitry in that block, (2) apply any of several clock signals to the utilization circuitry in that block, and (3) connect to the similar module(s) of one or more adjacent blocks.

Abstract: The invention provides for indexing and cataloging of content on the Internet, as well as from other stores of information, may be performed by applying a process that employs an orthogonal corpus, or corpora, of information, such as an Encyclopedia. To this end, the processes described herein identify the topics discussed within the corpus. The process also identifies within the corpus a set of keywords that are relevant to the topics presented in the corpus. The keywords associated with a topic may be employed to identify documents stored in another database that are related to the topic. A graphical representation of the index of topics found in the corpus may then be generated, with individual topics operating as links to these related documents. Thus, a user interested in reviewing content in the corpus related to a certain topic, may also activate a link in the graphical representation of the index to access other documents that have been identified as related to the topic of interest to the user.

Abstract: Compiler flows are provided that can produce functionally equivalent field programmable gate arrays (“FPGAs”) and structured application-specific integrated circuits (“structured ASICs”). The flows may include feeding back design transformations that are performed during either flow so that a later performance of the other flow will necessarily include the same transformations, thereby helping to ensure functional equivalence. The flows may include a comparison of intermediate results in order to prove that functional equivalence is being achieved.

Abstract: A system estimates flow parameters associated with a fluid flow encountering a bluff body. The system includes multiple sensors distributed on a surface of a bluff body. The system further includes input circuitry and a sensor processing unit. The input circuitry receives a signal from each of the multiple sensors. The sensor processing unit determines noise levels associated with each of the multiple sensors due to the fluid flow encountering the bluff body. The sensor processing unit further assigns weights to each of the multiple sensors based on the determined noise levels and estimates the fluid flow direction based on the assigned weights.

Abstract: An I/O interface for configuring hard IP embedded in a FPGA includes a register load signal, a CSR initialization signal, and a register data signal. After programming the DPRIO registers, the register data controls the operation of the hard IP block. The interface supports both CSR load mode and the MDIO interface. The user-friendly I/O interface eliminates all requirements on the end-user and is virtually transparent to the end-user.
