Simulation for M14K, M14Kc microMIPS processor coresModels available in OVP from March 2010.In November 2009 MIPS announced a new range of 32 bit cores and its new microMIPS very efficient compressed instruction set. There are initially two cores, the M14K, and M14Kc with cache controller and virtual memory support. Datasheets for the M14K are available here and for the M14Kc here. Imperas and MIPS working togetherImperas has been working with MIPS on Instruction Accurate simulation for these new cores. OVP is now making available the simulation fast models of these cores as part of the MIPS-Verified partnership program.The M14K and M14Kc models are available for free download from this OVPworld.org website and are the first simulation models available that simulate this new microMIPS instruction set. The instruction accurate simulation models work with the OVP and Imperas simulators and come with interfaces to be used in C, C++, SystemC, and TLM2.0 virtual platforms. OVP MIPS models have been tested to work with leading simulation solutions from Cadence, Mentor, Synopsys, and OSCI. The fastest recorded speed for OVP MIPS32 processor models on a 3GHz desktop PC is running the peakspeed1 benchmark at 1228 MIPS. The speed of models depends on the complexity of the platforms and the instruction workload being performed. Users report speeds of many 100's MIPS running real workloads. Customer feedback includes "Finding that the simulation performance of the Imperas/OVP model was 50 times faster than our previous solution opens up new possibilities for us in software testing, and enables us to increase our test coverage and product reliability". OVP M14K/M14Kc model featuresThe OVP models are normally provided pre-compiled as a binary, but are also available as open source under the Apache 2.0 license. The models are configurable for the different available options and can be used in single core or multicore platforms.M14K/M14Kc bare metal platformsIncluded with the release of the new models is a bare metal platform that can be loaded with a compiled microMIPS binary. This can run the binary and will provide any console output e.g. 'printf' to a shell. A GDB debugger can be connected to the platform to enable source code debug of the microMIPS code. Also an Eclipse IDE can be used to provide graphical debug of the M14K/M14Kc software.The platform is provided as source and so like any other OVP platform you can add other peripheral components such as UARTs, VGA, LCD, interrupt controllers, ethernet, USB etc. You can also instance any other OVP processors making the platform fully multicore. To have a look at this platform, install the 'M14K bare metal platforms package' called OVPsim_demo_M14K for your Linux or Windows host. When installed have a look at the *Imperas\Demo\OVPsim_M14K directory. Read the README.txt, and run with RUN_OVPsim_M14K_dhrystone.bat or debug with DEBUG_GDBRSP_OVPsim_M14K_dhrystone.bat etc. Download M14K/M14Kc/microMIPS models, platforms and toolsIn the right hand side of this page you will see links for the specific downloads that are available for these new processor cores. There are currently the models and platforms. There is also a link to get the GNU compiler and debugger tools.In the next few weeks we will also include downloads for Eclipse IDE usage and other example platforms. We will also include links to specific presentations and videos that relate to these new cores. Below is information relating the other MIPS-Verified OVP models of MIPS processors. OVP Download for MIPS 4K, 24K, 34K, 74K, 1004K, 1074K processorsFor first time MIPS download page, go here.For videos related to MIPS Malta Platforms running Linux and debugging user applications, please click here. MIPS-Verified(tm) - all processors models of MIPS Technologies processors available from this site are now MIPS-Verified(tm). Please see the associated press release for more information. On the right you will see the different downloads available for MIPS cores - from simple single processor platforms running benchmark applications through to multi-core examples and also a Malta platform that boots Linux. Also - there is the download of the models themselves - including many examples of using them - and its source is available in the Library section. Also there are GCC, GDB etc toolchains you will need to compile and run applications. Using the OVP MIPS modelTo use the MIPS model you will need several things downloaded. You will need to download a) the OVPSim simulator, b) the MIPS model itself (included as binary in the OVPsim package), and c) if you don't already have the toolchain to compile up applications, you will need that too... And then take a look at some of the examples - they provide pointers as to what is needed for starter platforms. Then you will need to write your own platform.c file, application.c and when compiled - you will be all set.MIPS Demo Slide Presentation View LargeYou could walk through this presentation to get a feel for how easy it is to use the MIPS model.
