@ -3,7 +3,7 @@ Core device
The core device is a FPGA-based hardware component that contains a softcore CPU tightly coupled with the so-called RTIO core that provides precision timing. The CPU executes Python code that is statically compiled by the ARTIQ compiler, and communicates with the core device peripherals (TTL, DDS, etc.) over the RTIO core. This architecture provides high timing resolution, low latency, low jitter, high level programming capabilities, and good integration with the rest of the Python experiment code.

While it is possible to use all the other parts of ARTIQ (controllers, master, GUI, result management, etc.) without a core device, many experiments require it.

Experiments interact with an environment that consists of devices, parameters, arguments and results. Access to the environment is handled by the class :class:`artiq.language.environment.EnvExperiment` that experiments should derive from.

After the experiment has finished executing, the results are written to a HDF5 file that resides in ``~/artiq-master/results/<date>/<time>``. Open that file with HDFView or h5dump, and observe the data we just generated as well as the Git commit ID of the experiment (a hexadecimal hash such as ``947acb1f90ae1b8862efb489a9cc29f7d4e0c645`` that represents the data at a particular time in the Git repository). The list of Git commit IDs can be found using the ``git log`` command in ``~/artiq-work``.
