2. OVP => Open Virtual Platforms A FREE and OPEN platform for SoC and MPSoC develop  Hardware develop 。 Existing modules 。 Self-design modules(in C)  Software develop 。 Co-simulation Like Coware(System C), but the no GUI and the syntax is different. Can be run on Linux and Windows XP, and can run with GCC and GDB

3. Hardware platform  Written in proprietary languages and libraries  Low level, cycle accurate  Details of the hardware  Like System C Software platform  Fast,but not detail  Focus on the instructions and code But in embedded system develop, both of then is important.

4. The growing challenge for SoC  The growth of the hardware complexity  The embedded software need more fast hardware The solution is multi-core – MPSoC  “Von Neumann is a poor use of scaling –all the energy is going on the communication between the processor and the memory. Its much better to use 20 microprocessors running at 100MHz than one at 2GHz” - Hugo de Man, IMEC

5. Embedded software is the big problem with MPSoC products  Software co-design and co-simulation now is a important issue  "30 to 50 per cent of R&D budgets are spent on software, and the cost is rising 20 per cent a year. The software effort overtakes the hardware effort at 130nm.“ - Jack Browne, MIPS Technologies

6. So OVP give a platform for multi-core and the software co-simulation.

7. Create your own environment  Like system C, you can integrate your own IP into the environment Contract Service Provider  Like ARM, ARC, MIPS….etc.  Design can use those modules to develop the MPSoC in free and not illegal http://www.ovpworld.org/about_partners.php

9. Both of then are free, but  Great for multiprocessor platforms with arbitrary shared and local memory configurations.  Simulation of processors with virtual memory with almost no performance penalty.  Peripheral Simulation Engine (PSE)  Fast 。 2,000 MIPS

10. OVP comprises three components  OVP modules  OVP API  OVP sim OVP modules  C source of models written to C OVP APIs  Processor models of ARM, ARC, MIPS, OpenRisc, PowerPC, Renesas, SPARC, x86, …  Peripheral models of standard embedded devices  Example embedded platforms in C, C++, SystemC, TLM2.0 。 Including full platforms that boot operating systems like uClinux, Linux, Nucleus, MicriumuC/OS-II, FreeRTOS

11. OVP API has 4API for use  ICM – to create the platform  VMI – to create the processor  PPM and BHM – to setup the modules OVP sim use to simulation  Simple C API, ICM API can be use  System C,C++,TLM modules also can be use

16. OVP can be use in hardware/software co simulation Multiprocessor can be run and simulation But for us, we need to rewrite the IP into C or System C modules, the cost here is in large Maybe can be use  Demo  Simple verification
