  • Apparatus and method for implementing watchpoints and breakpoints in a data processing system
    Patent number: 5754839
    Abstract: An apparatus and method for implementing watchpoints and breakpoints in a data processing system (110). In one embodiment, a pipelined processor (110) performs each instruction of a program. One or more watchpoints are associated with the instructions. The processor includes a history buffer (50) for storing processor state values at the time when each of the instructions was executed, until a predetermined time. Watchpoint information associated with a particular watchpoint is also stored in the history buffer (50), in association with the processor state values, such that the processor state is changed and the watchpoint is announced at the predetermined time. The watchpoint information may include increment/decrement information for one or more counters (41, 42). Breakpoint information may also be stored in history buffer (50).

  • Method and intelligent digital beam forming system responsive to traffic demand
    Patent number: 5754139
    Abstract: An intelligent digital beam former (10) in conjunction with a satellite based array antenna (20) provides a plurality of dynamically controllable antenna beams (52) for communication with subscriber units (90) in response to demand for communication services. Geographic portions within the satellite's footprint that have a higher-demand for communication services are dynamically provided additional antenna beams while geographic portions having a lower demand for communication services are provided less antenna beams. When used on a non-geostationary satellite, the digital beam forming coefficients are dynamically adjusted to steer the antenna beams to maintain their ground location. The antenna beams are also shaped to help optimized geographic coverage.

  • Method and system for overhead bandwidth recovery in a packetized network
    Patent number: 5751723
    Abstract: In a packet network, message packets (130) are comprised of vacant or unused bits for future system enhancements or for remedying unknown design oversights or utilizing vacant portions of fixed length data packets. Furthermore, message packets (130) comprise a message type identifier distinguishing message architecture. A transmit and receive packet network node (100) maintains an unused bit catalog (125) listing vacant or unused bits of particular message packet types. When a message packet type having vacant or unused bits is detected propagating through the packet network, background data is retrieved from a transmit background data queue (115) and interleaved into such message packets to form enriched message packets (130') for transportation through the packet network. Receiving packet network nodes (100) detect enriched message packets (130') and extract and buffer the background data.
