  • Asynchronous, independent and multiple process shared memory system in an adaptive computing architecture
    Patent number: 7577799
    Abstract: The present invention provides a system and method for implementation and use of a shared memory. The shared memory may be accessed both independently and asynchronously by one or more processes at corresponding nodes, allowing data to be streamed to multiple processes and nodes without regard to synchronization of the plurality of processes. The various nodes may be adaptive computing nodes, kernel or controller nodes, or one or more host processor nodes. The present invention maintains memory integrity, not allowing memory overruns, underruns, or deadlocks. The present invention also provides for “push back” after a memory read, for applications in which it is desirable to “unread” some elements previously read from the memory.
    Type: Grant

  • Method and system for real-time multitasking
    Patent number: 7360216
    Abstract: A method of selecting tasks for execution on a processing node is provided. A plurality of indications of execution times corresponding to a first plurality of tasks is received. Also, a plurality of indications of maximum allowable latencies corresponding to the first plurality of tasks is received. At least a subset of the first plurality of tasks is selected for execution on the processing node based on the plurality of indications of execution times and the plurality of indications of maximum allowable latencies.
