| Abstract: | In recent years we have seen the rise of the heterogeneous System on Chip. It is no longer uncommon to include multiple divergent cores in a single chip. These cores might be from very different vendors who each ship simulators for their core. This makes creating a simulator of the whole chip difficult since these simulators can not be efficiently combined. Most current approaches do not allow the user to take advantage of the multi-threaded capability of such systems or they do not allow the user to make a trade off between simulation accuracy and performance. The goal of the Handfish framework is to facilitate the creation of heterogeneous multi-core System on Chip simulators. The focus lies on developing techniques to combine simulators and to allow them to take advantage of the multi-threaded nature of today's host computers. Since not all simulations need the highest level of accuracy, the framework allows the strictness to be decreased in exchange for more performance. This is achieved by changing and/or tuning the synchronization strategy of the constituent simulators. A simulation algorithm has been developed that uses networking patterns to communicate between the components and that allows different instruction set simulators to be combined into a single simulator with a tunable level of accuracy. The implementation of this algorithm is combined with a simple instruction set simulator to get a better overview of the effects of changing the simulation strictness and the performance of the framework. The simulator framework has also been used to combine two different instruction set simulators to create a heterogeneous simulator of a systems with two digital signal processors and one general purpose processor besides various homogenous simulators. |
