| static void SoCpuDevice::exitClass | ( | ) | [static] |
This function frees the allocated memory.
Reimplemented from SoDevice.
| static SoCpuDevice* SoCpuDevice::findFirstAvailableDevice | ( | ) | [static] |
Returns the first available device found in the system.
| SoCpuDevice::ProcessorArchitecture SoCpuDevice::getArchitecture | ( | ) | const [inline] |
Returns the architecture of the processor.
| virtual unsigned long long SoCpuDevice::getAvailableMemory | ( | ) | const [virtual] |
Returns the current available memory of this device in bytes.
Implements SoDevice.
| unsigned int SoCpuDevice::getCacheSize | ( | int | cacheLevel | ) | const |
Returns the size of the cache on this device in bytes.
Note: On Microsoft Windows platforms this function only returns a valid number on Windows XP SP3 and newer.
- Parameters:
-
cacheLevel The cache level can be 1, 2, or 3.

Note: On Microsoft Windows platforms this function only returns a valid number on Windows XP SP3 and newer.
Implements SoDevice.
| int SoCpuDevice::getSSELevel | ( | ) | const [inline] |
Returns the SSE instruction level available on this device.
| unsigned long long SoCpuDevice::getTotalMemory | ( | ) | const [inline, virtual] |
Returns the total memory of this device in bytes.
Implements SoDevice.
| bool SoCpuDevice::hasMMX | ( | ) | const [inline] |
Returns true if MMX instructions are supported on this device.
| bool SoCpuDevice::hasSSE | ( | ) | const [inline] |
Returns if SSE instructions are supported on this device.
| static void SoCpuDevice::initClass | ( | ) | [static] |
This function detects the CPU available in the system.
| bool SoCpuDevice::isActive | ( | ) | const [inline] |
Returns true if the CPU is active in the system.
