Faster than Real-Time - laysim-gr740-mdbt
laysim-gr740-mdbt (Multi-thread DBT) I'm really proud to release laysim-GR740 v1.2 with laysim-gr740-mdbt . laysim-gr740-mdbt is a new parallel GR740 processor emulator which adopts the multi-thread framework with DBT through 2 years development by KARI. It can satisfy the real-time performance of GR740 on a high-end PC such as Intel i9-11900K @5GHz. Below Figure is a graph comparing the real-time performance and cycle accuracy of the most representative tests among all tests. laysim-gr740-dbt outperforms the real-time performance of GR740 on Dhrystone with 334.69%, and it can meet the real-time performance on Whetstone with 120.19%. But laysim-gr740-dbt cannot meet the real-time performance for some RTEMS 5.1 SMP examples which utilize almost 100% CPU load with 4 cores and its execution time is more than 5 seconds under the SMP environment. Only laysim-gr740-mdbt can meet the real-time performance of GR740 under RTEMS SMP environment.
