ARC® xCAM Modeller
Extends Model Cycle Accuracy to 100 Percent for ARC IP
ARC® xCAM products work with the ARChitect™ Processor Configurator to automatically provide 100% cycle accurate models that reflect SoC designers' specific hardware configurations of ARC IP. These models allow design verification and provide detailed performance analysis of critical routines before finalizing the hardware design. With the ARC xCAM tool, multiple models are generated to compare alternative approaches against specific code early in the design process, assisting in choosing optimal an configuration.

Highlights
100% Cycle-Accurate Models
Models are automatically available within minutes of finishing a configuration. Code can be tuned on actual processor configurations being considered, and hardware can be tested and verified. And, exact models match to CPU configuration so there is no risk of the model and RTL getting out of sync.
Unlimited Model Generation
Quickly and easily iterate and test unlimited combinations of code algorithms and processor configurations to find right code size/performance tradeoffs.
Highly Productive
The ARC xCAM tool is integrated with the MetaWare Development Toolkit for ease of use. Detailed cycle information is provided to guide assessments and profiling, or SystemC models can connect to wider co-development tool flows to help productivity. Users can run the same software on different models and determine which CPU configuration provides best software performance.
Versatile
The ARC xCAM tool is useful for algorithm optimization or module-level development. It can analyze “hot spots” in software - areas that might be candidates for optimization or custom instructions. And, the ARC xCAM tool can function in “CPU island” mode (C model) or as a part of an entire system (SystemC model).
Integrated Solution
Seamlessly integrated with the ARChitect Processor Configurator and MetaWare Debugger. The ARC xCAM tool also can perform cycle accurate simulation within the OSCI SystemC/CoWare environments.
Shortens Design Time
The ARC xCAM tool enable the early development of software, early verification of design, and fast hardware iterations.

ARChitect™ Integration
xCAM installs within the ARChitect framework to generate cycle-accurate models. Once installed, the modelling component can be added to the processor design within ARChitect and options set. ARChitect then builds a 100% cycle-accurate model.

xCAM Models Track Your Configurations Automatically
Upon completion of the ARC IP configuration, ARChitect uses xCAM to add a step into the build process generating a cycle-accurate model that reflects the user's configuration automatically.

MetaWare Debugger Integration
The xCAM models operate as a target within the MetaWare Debugger. Using xCAM’s 100% cycle accurate models are as simple as using an ISS, an ARCangel prototyping system or actual hardware.

- At any time during the run, we can access the following profiling information:
- Forward cycle counts
- Backward cycle counts
|
- Mispredicts
- Instruction Counts
|
- Profiling data can be viewed:
- Per function – to determine function with the most cycle counts.
- Per line of source or disassembly – to find candidates for custom instructions within a function.
- Per count – ordered from highest to lowest counts across the entire application.
