  • Patent number: 5815667
    Abstract: The present invention is directed, in general, to network connectivity, and more specifically to circuits and methods for intelligent acknowledgment-based flow control in a processing system network. The present invention concerns governing transmission of data packets and reception indicia by a transmission circuit over a network. Detector circuitry is included and is operative to (1) monitor a first latency characteristic of the network that is indicative, at least in part, of a utilization level of the network; and (2) monitor a second latency characteristic indicative, at least in part, of an efficiency level associated with transmission of the reception indicia by the transmission circuit. Control circuit is further included and is associated with the detector circuitry and the transmission circuit.

  • Patent number: 5689707
    Abstract: The invention utilizes expiration events and dependent pointers to indicate when the corresponding memory allocation should be de-allocated. Expiration events are occurrences that indicate corresponding memory allocations should be de-allocated prior to the occurrence of the event. Dependent pointers are pointers to currently allocated blocks of computer memory. These dependent pointers indicate that the corresponding computer memory allocation should be de-allocated prior to the de-allocation of the computer memory allocation referred to by the dependent pointer. Using memory management functions, the expiration events and dependent pointers are stored in a memory allocation table along with filenames and line numbers indicating where the request was made. At given points in the program, the memory allocation table is checked for memory leaks.
