Nowadays, the release of SoC products has come to a burst. Time-to-market of these products has been shortened to an extreme, nearly 8 to 12 months. To reduce production period, hardware architects generally combine well-tuned IP cores in their designs. To guarantee the process of SoC software development, which will finally decide the release time of products, a fast prototyping simulation platform...
Faced with increasingly large multicore chip designs, architects need fast and accurate simulations for their exploration of design spaces within a limited simulation time budget. In multithreaded applications, threads cannot run simultaneously. Sampling is commonly used to reduce simulation time, but conventional sampling barely detects the instantaneous program variations of synchronization events...
Full-system simulators are extremely useful in evaluating design alternatives for multicore. However, state-of-the-art multicore simulators either lack good extensibility due to their tightly-coupled design between functional model (FM) and timing model (TM), or cannot guarantee cycle-accuracy. This paper conducts a comprehensive study on factors affecting cycle-accuracy and uncovers several contributing...
