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： Method and apparatus for implementing a program language description of a circuit design for an integrated circuit is described. In one example, a program is specified using a concurrent programming language. The program includes programming constructs that define a plurality of processes and a plurality of communication channels. A hierarchy of elements that classify the programming constructs of the program are generated to produce a transformed representation. A hardware description language (HDL) representation of the circuit design is generated from the transformed representation by translating the hierarchy of elements to a hierarchy of HDL constructs that implements the plurality of processes and the plurality of communication channels in hardware.
