摘要： Disclosure is made of approaches for mapping an electronic design specification to an implementation. In one approach, quality metrics are associated with functional units of the design, and the functional units are mapped to respective initial implementations. For each functional unit a respective quality indicator is determined based on the mapping. The quality indicator specifies a degree to which the functional unit achieves the associated quality metric. At least one of the functional units is selected for remapping based on the quality indicator of that functional unit or the quality indicator of another functional unit. An alternative implementation to the initial implementation is selected for each selected functional unit to improve the quality indicator. The selected functional unit is remapped to the selected alternative implementation.

摘要： Automatic queue sizing for data flow applications for an integrated circuit is described. Queue sizes for queues of a dataflow network are initialized to a set of first sizes for running as distributed actors without having to have centralized control. If it is determined there is a deadlock, causes for the dataflow network being deadlocked are analyzed with a controller coupled thereto to select a first actor thereof. The first actor of the dataflow network is selected as being in a stalled write phase state. Queue size is incremented for at least one queue of the queues to unlock the first actor from the stalled write phase state. The running, the determining, the analyzing, and the incrementing are iteratively repeated to provide a second set of sizes for the queue sizes sufficient to reduce likelihood of deadlock of the data flow network.

摘要： Systems and methods detect a communication received at receiving antennas from transmitting antennas. Each transmitting antenna transmits a symbol in a constellation. A sphere detector performs a depth-first search until the depth-first search terminates in response to a terminate signal requesting the result from the sphere detector. The depth-first search evaluates respective distances of one or mode leaf nodes in response to the communication received at the receiving antennas. The depth-first search selects the result from these nodes in response to the respective distances. The result includes a selected leaf node that identifies a corresponding symbol in the constellation for each transmitting antenna, with this symbol detected as transmitted by the transmitting antenna.

摘要： Configuration memory cells in an integrated circuit (IC) may be corrupted by cosmic radiation and other sources, causing improper operation of the IC. Reliability of an IC is improved by refreshing subsets, such as frames, of the configuration data according to a schedule that has one subset being refreshed more frequently than another subset. For each subset of the configuration data, a respective indicator is determined that indicates whether a subset of configuration memory of the IC requires refreshing with the subset of configuration data. The indicator may be a probability that corruption of the subset of configuration memory results in improper operation. A schedule for refreshing the subsets of configuration memory is generated from the indicators. The subsets of configuration memory are refreshed according to the schedule, with one subset being refreshed more frequently than another subset.
