    摘要: A deadlock free synchronization synthesizer for must-happen-before relations in at least two parallel programs or at least two threads each having multiple code segments has an input device to specify a synchronization point to involving code segments for each parallel program or thread and must-happen-before relations to the synchronization point, an analyzing module connected to the input device to detect existence of a deadlock in the parallel programs by using the must-happen-before relations, and a synthesizing module connected to the analyzing module to synthesize a practice code corresponding to the parallel programs if the deadlock existence detection is negative.

    摘要: The present invention discloses a high-parallelism synchronization method for multi-core instruction-set simulation. The proposed method utilizes a new distributed scheduling mechanism for a parallel compiled MCISS. The proposed method can enhance the parallelism of the MCISS so that the computing power of a multi-core host machine can be effectively utilized. The distributed scheduling with the present invention's prediction method significantly shortens the waiting time which an ISS spends on synchronization.

    摘要: The present invention discloses a cycle-count-accurate (CCA) processor modeling, which can achieve high simulation speeds while maintaining timing accuracy of the system simulation. The CCA processor modeling includes a pipeline subsystem model and a cache subsystem model with accurate cycle with accurate cycle count information and guarantees accurate timing and functional behaviors on processor interface. The CCA processor modeling further includes a branch predictor and a bus interface (BIF) to predict the branch of pipeline execution behavior (PEB) and to simulate the data accesses between the processor and the external components via an external bus, respectively. The experimental results show that the CCA processor modeling performs 50 times faster than the corresponding Cycle-accurate (CA) model while providing the same cycle count information as the target RTL model.
