摘要： Methods and circuitry for implementing high speed first-in first-out (FIFO) structures. In one embodiment, a FIFO is disclosed that allows the frequency of one clock, e.g., the write clock, to be different than (e.g., half) that of the other (read) clock. In another embodiment a FIFO is presented that can be set and/or reset asynchronously. Other embodiments are disclosed wherein the read and write pointers are effectively monitored to ensure proper timing relationship, to detect loss of clock as well as to detect other abnormal FIFO conditions.

摘要： A polymer memory system stores digital data in dipole moments of polymer memory cells. Apparatus is disclosed having polymer memory cells provided within an LCD display chamber. Embodiments provide for a high degree of integration the polymer memory system and a display system by providing polymer memory cells within the chamber. The memory cells may be located in non-viewable regions of the chamber. Thus, the memory cells provide only limited interference with the image-bearing functions of the display (if they interfere at all) but provide an extra dimension of functionality to the display.

摘要： A method of optimizing a data path in a multi-port bridge for a local area network (LAN) includes steps of: identifying a data path through the multi-port bridge wherein the data path includes a plurality of stages in a serial arrangement, wherein each stage performs a corresponding operation on data received from the LAN by the multi-port bridge; identifying a stage in the data path wherein the identified stage requires a period of time to perform its corresponding operation which is longer than any other stage; and subdividing the identified stage into two or more subdivided stages wherein the operations performed by the subdivided stages collectively perform the operation associated with the identified stage and wherein each of the two or more subdivided stages requires a period of time to perform its corresponding operation which is shorter than the period of time required for the identified stage to perform its corresponding operation. The method can include determining a bandwidth required for the multi-port bridge; and determining a frequency for a clock signal based upon the bandwidth. The method can also include repeatedly subdividing selected stages until a slowest stage in the data path is operable according to the clock signal. The invention results in a beneficial trade-off in which bandwidth for the multi-port bridge and latency are both increased.

摘要： Merchants create ecommerce-enabled ad units advertising items offered by the merchants. The ad units contain functionality enabling customers to purchase the items by interacting with the ad units. The ad units have associated bid prices that the merchants agree to pay for sales through the ad units. The merchants provide the ad units to a broker. The broker publishes the ad units on web pages provided by publishers. A customer receiving a web page interacts with the ad unit to purchase the item. During the interactions, the broker dynamically updates the ad unit to carry out the transaction. The broker collects the bid price from the merchant and shares it with the publisher that published the page on which the ad unit appeared.
