Model Information


This page provides detailed information about the OVP Fast Processor Model of the Renesas V850E1 core.
Processor IP owner is Renesas (formerly NEC). 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 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.

Parallel Simulation using Imperas QuantumLeap


Traditionally, processor models and simulators make use of one thread on the host PC. Imperas have developed a technology, called QuantumLeap, that makes use of the many host cores found in modern PC/workstations to achieve industry leading simulation performance. To find out about the Imperas parallel simulation lookup Imperas QuantumLeap. There are videos of QuantumLeap on ARM here, and MIPS here. For press information related to QuantumLeap for ARM click here or for MIPS click here.
Many of the OVP Fast Processor Models have been qualified to work with QuantumLeap - this is indicated for this model below.

Embedded Software Development tools


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.

Instruction Set Simulator (ISS) for Renesas V850E1


An ISS is a software development tool that takes in instructions for a target processor and executes them. The heart of an ISS is the model of the processor. Imperas has developed a range of ISS products for use in embedded software development that utilize this fast Fast Processor Model. The Imperas Renesas V850E1 ISS runs on Windows/Linux x86 systems and takes a cross compiled elf file of your program and allows very fast execution. The Renesas V850E1 ISS also provides access to standard GDB/RSP debuggers and connects to the Eclipse IDE and Imperas debuggers.
