Overview
The ncDeviceOption_t enumeration defines neural compute device options that can be read with ncDeviceGetOption() or set with ncDeviceSetOption().
| Constant | Option Type | Possible Values | Description |
|---|---|---|---|
| NC_RO_DEVICE_THERMAL_STATS | float[ ] | Any | Device temperatures in degrees Celsius. These temperatures are the maximum temperatures for the last NC_THERMAL_BUFFER_SIZE seconds. The size of this array is also NC_THERMAL_BUFFER_SIZE. |
| NC_RO_THERMAL_THROTTLING_LEVEL | int | 0, 1, 2 | 0: No limit reached. 1: Lower guard temperature threshold of chip sensor reached; short throttling time is in action between inferences to protect the device. 2: Upper guard temperature of chip sensor reached; long throttling time is in action between inferences to protect the device. |
| NC_RO_DEVICE_STATE | int | Values in the ncDeviceState_t enumeration | The state of the device and the associated ncDeviceHandle_t struct. |
| NC_RO_DEVICE_CURRENT_MEMORY_USED | int | Unbounded positive int | The current memory in use on the device in bytes. This value divided by NC_RO_DEVICE_MEMORY_SIZE is the percent of memory in use. |
| NC_RO_DEVICE_MEMORY_SIZE | int | Unbounded positive int | The total memory available on the device in bytes. |
| NC_RO_DEVICE_MAX_FIFO_NUM | int | Unbounded positive int | The maximum number of FIFOs that can be allocated for the device. |
| NC_RO_DEVICE_ALLOCATED_FIFO_NUM | int | Unbounded positive int | The number of FIFOs currently allocated for the device. |
| NC_RO_DEVICE_MAX_GRAPH_NUM | int | Unbounded positive int | The maximum number of graphs that can be allocated for the device. |
| NC_RO_ALLOCATED_GRAPH_NUM | int | Unbounded positive int | The number of graphs currently allocated for the device. |
| NC_RO_DEVICE_OPTION_CLASS_LIMIT | int | Unbounded positive int | The highest option class supported. |
| NC_RO_DEVICE_FW_VERSION | unsigned int[4] | [major, minor, hardware type, build number] | The version of the firmware currently running on the device. |
| NC_RO_DEVICE_DEBUG_INFO | char[ ] | Debug info | Not yet implemented. A null-terminated character array containing more detailed debug info when the result of a function call was NC_MYRIAD_ERROR. The maximum size of this array is NC_DEBUG_BUFFER_SIZE. |
| NC_RO_DEVICE_MVTENSOR_VERSION | unsigned int[2] | [major, minor] | The version of the mvtensor library that was linked with the API. |
| NC_RO_DEVICE_NAME | char[ ] | Device name | A null-terminated character array containing the internal name of the device. The maximum size of this array is NC_MAX_NAME_SIZE. |
| NC_RO_DEVICE_MAX_EXECUTORS_NUM | int | Unbounded positive int | Maximum number of executor threads supported on the device. The graph option NC_RW_GRAPH_EXECUTORS_NUM should not exceed this maximum value. |
| NC_RO_DEVICE_HW_VERSION | int | Values in the ncDeviceHwVersion_t enumeration | The hardware version of the device. |
Notes
- Options prefixed with ‘NC_RW’ have read/write permission and are both gettable and settable.
- Options prefixed with ‘NC_RO’ have read-only permission and are only gettable.
