  • Patent number: 7721236
    Abstract: Methods and apparatus for estimating the propagation delay along a logical signal path are described herein. The methods and apparatus account for the behavior of multi-stage logic gates along a signal path, initial input transition times, inter-stage fanouts, as well as different logic gate types. The methods and apparatus convert signal transition features into an effective fanout to provide estimates of gate delay dependencies on input slope and gate logic topology.

  • Patent number: 6216220
    Abstract: The data processing system, a combination of multithreaded architecture and a VLIW (Very Long Instruction Word) processor is adapted to process plural threads. The system uses multiple program counters for context-switching only a subinstruction which causes a long latency. A method is provided for processing instructions in a data processing system having an active thread block, a ready thread block and a waiting thread block, and a instruction execution block, for processing a plurality of threads. The method includes combining instructions issued from the respective active threads into one new instruction, each active thread having a plurality of instructions, and the issued instructions being used as subinstructions in the combined one instruction. The combined instruction as processed by the instruction execution block, while tracing contexts relating to the threads which provide the respective subinstructions by using multiple program counters.
