laysim-GR712RC v3.0 is being released, offering the same interface and functionality as laysim-GR740 v3.0 . 1. The previously separated versions (GUI, CLI, MMU, PERF) have been consolidated into a unified GUI/CLI version for improved usability. 2. The Linux guest environment is once again supported in the DBT versions. 3. Users can now modify the RAM and ROM sizes, as well as configure the CPU operating frequency. 4. All internal simulation modules for 1553B, GRCAN, CAN, and SpaceWire have been removed. External interface simulation is now available exclusively through loadable modules. 5. laysim-gr712rc-dbt shows significantly higher performance than the real-time performance of the GR712RC in all RTEMS 5.1 SMP tests. The evaluation version of laysim-GR712RC and documents are available for download via Google Drive .

I am pleased to announce the release of laysim-GR740 v3.0 , which has been developed through significant effort. The new version introduces the following changes and updates: 1. The previously separated versions (GUI, CLI, MMU, PERF) have been consolidated into a unified GUI/CLI version for improved usability. 2. Support has been added for the GUI-based laysim-gr740-mdbt . 3. The Linux guest environment is once again supported in the DBT/MDBT versions. (In this case, Linux employs an MMU with multiple page tables, and the simulator has been updated to support code cache retranslation on a page basis in response to self-modifying code.) 4. Users can now modify the RAM and ROM sizes , as well as configure the CPU operating frequency . 5. Support for GR740 silicon revision 0 has been discontinued; only revision 1 is now supported. 6. All internal simulation modules for 1553B, GRCAN, CAN, and SpaceWire have been removed. External interface simulation is now available exclusively through ...
