    - RTEMS5.1 smpmrsp01 : 286.99 MIPS (the real-time performance is 253.69%)



2. Support the User Loadable Modules

▶ Support loadable modules for UART, I2C, SPI, GPIO, I/O, external SpW nodes, 1553B RTs, and CAN nodes. 


3. Support the Shared Library

▶ laysim-GR712RC also supports the shared library that can be integrated in an existing simulator. (save/restore are supported.)


4. Embedded Source Level Debugger

▶ laysim-GR712RC includes the embedded source-level debugger, so it is possible to debug the GR712RC SMP applications without GDB.


5. Fully Support for AIR and XtratuM Hypervisors

▶ laysim-GR712RC also supports AIR/GMV hypervisor awareness, so it possible to debug the partitions of AIR with the embedded source-level debugger.



6. Support Code Coverage with RTEMS COVOAR

▶ laysim-GR712RC supports the code coverage as same format of TSIM3-LEON3.

I'm Jong-Wook Choi from KARI (Korea Aerospace Research Institute). I'm an on-board flight software engineer in KARI. I've developed the flight software for KOMPSAT-2/3/5/3A, CAS-500 and GEO-KOMPSAT-2A/2B. Currently I involve in developing of the flight software for KOMPSAT-6/7/7A, and KPLO (Korean Pathfinder Lunar Orbiter). For many years, flight software (FSW) has been developed and verified using the software test bed (STB) environment based on the real hardware in KARI. During the development of FSW on the STB, we have experienced lots of annoying problems such as delayed deliver of target hardware, limited concurrent access to the STB from software engineers, and the time and cost to create multiple STBs for different satellites. Thus, software-based satellite simulators have been developed from the beginning of a satellite project to avoid these issues. The software-based simulator enables the FSW to be developed concurrently with the satellite hardware from the in

laysim-GR740 Quad Core Processor Emulator laysim-GR740 consists of three types of emulators: laysim-gr740 ,  laysim-gr740-dbt  and  laysim-gr740-mdbt . laysim-gr740 is a graphic user interface (GUI)-based and cycle-accurate emulator for the GR740 quad core processor based on interpretation method. It includes an embedded source-level debugger and supports MMU for Linux-SMP and XtratuM-SMP. laysim-gr740-dbt is a GUI-based high-performance and cycle-approximate processor emulator with dynamic binary translation method. 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. All  laysim-gr740 ,  laysim-gr740-dbt  and  laysim-gr740-mdbt  support Windows and Linux x64 platform including CentOS 7/8, Ubuntu 18.04 and Debian 10.3. Also two types of CLI (Command Line Interface) version, laysim-gr740
