Cortex-M4 | SystemC Models

Detailed information about the SystemC TLM2 Fast Processor Model of the ARM Cortex-M4 core.
Processor IP owner is ARM Holdings. More information is available from them here.

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 has been run through an extensive QA and regression testing process.

Overview of Fast Processor Model
