xCAM Cycle Accurate Models
Automatically Generated 100% Cycle Accurate Models of 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 software before finalizing the hardware design. With ARC xCAM, multiple models are generated to compare alternative approaches against specific code early in the design process, assisting in choosing an optimal configuration.

ARChitect Integration
xCAM installs within the ARChitect IP Configurator to generate cycle-accurate models. Once installed, the modeling component can be added to the processor design within ARChitect and options set. ARChitect then builds a 100% cycle-accurate model in minutes.

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.

Debugger Integration
The xCAM model operates as a target within GDB and 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, access the following profiling information:
- Forward cycle counts
- Backward cycle counts
|
- Mispredicts
- Instruction Counts
|
- 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.
