This page provides detailed information about the SystemC TLM2 Fast Processor Model of the Renesas r8c core.
Processor IP owner is Renesas (formerly Mitsubishi).
OVP Fast Processor Model is written in C.
Provides a C API for use in C based platforms.
Provides a native C++ interface for use in SystemC TLM2 platforms.
The model is written using the OVP VMI API that provides a Virtual Machine Interface that defines the behavior of the processor.
The VMI API makes a clear line between model and simulator allowing very good optimization and world class high speed performance.
The model is provided as a binary shared object and is also available as source (different models have different licensing conditions). This allows the download and use of the model binary or the use of the source to explore and modify the model.
The model has been run through an extensive QA and regression testing process.
This model executes instructions of the target architecture and provides an interface for debug access.
An interface to GDB is provided and this allows the connection of many industry standard debuggers that use the GDB/RSP interface.
For more information watch the OVP video here.
The model also works with the Imperas Multicore Debugger and advanced Verification, Analysis and Profiling tools.
