  • Publication number: 20140380257
    Abstract: A technique for generating pushdown data comprises performing logical pushdown of circuit elements and nets and detecting physical pushdown based on partition boundary crossings. Geometry associated with one logical level may be used as a keep-out region for the same physical layer when generating physical design of a different logical level. The technique may advantageously enable concurrent design in both top-level and low-level physical design phases, thereby reducing overall design cycle time in developing an integrated circuit.

  • Patent number: 8718113
    Abstract: An apparatus for dehydrating a liquid sample of biological material has a microwave waveguide that is open to the atmosphere. It has a microwave generator, means for introducing a container of the material into the waveguide, means for evacuating the container, means for rotating the container and means for removing the container from the waveguide. It can include means for moving the container through the waveguide and for sealing it. In a dehydration method, a container of the liquid sample is put into the open waveguide, evacuated, rotated at high speed and microwaved. The container of dehydrated material is then removed from the waveguide. The apparatus and method are particularly suitable for dehydrating vaccines.

  • Patent number: 6535968
    Abstract: An apparatus, system, and method for speeding up data transfers while reducing bus contention during repeated consecutive read-write operations. By reducing the length of time during which selected data pulses are driven on the memory bus, a higher percentage of usage of the memory bus may be attained without increasing the likelihood of bus contention and resulting degradation or damage to the memory system. The selected data pulse is preferably the write data pulse driven on the memory bus by the memory controller. A zero bus turnaround protocol may be implemented. The memory controller may include interface circuitry and write control circuitry that outputs an associated control signal to a three-state buffer. The three-state buffer, after being enabled by the associated control signal, drives write data on a data line of a memory bus. The turn-on delay associated with the three-state buffer exceeds the turn-off delay also associated with the three-state buffer.

  • Patent number: 6119196
    Abstract: A method and apparatus for managing a buffer memory in a packet switch that is shared between multiple ports in a network system. The apparatus comprises a plurality of slow data port interfaces configured to transmit data at a first data rate between a slow data port and the buffer memory and a plurality of fast data port interfaces configured to transmit data at a second data rate between a fast data port and the buffer memory. A first level arbiter is coupled to the plurality of slow data port interfaces. The first level arbiter chooses an access request of one the slow data ports and outputs the access request. A second level arbiter is coupled to the plurality of fast data port interfaces and to the output of the first level arbiter. The second level arbiter chooses an access request from among a plurality access requests from the fast data port interfaces and the access request from the first level arbiter, and forwards the chosen access request to the memory.
