Ottenere informazioni generali sulla CPU con le funzioni esterne del API di SDL2
Da Gambas-it.org - Wikipedia.
La libreria SDL2 fornisce funzioni per conoscere alcune caratteristiche generali della CPU utilizzata.
A tal fine sarà necessario servirsi della seguente libreria condivisa: "libSDL2-2.0.so.0.3000.0 ".
Mostriamo un semplice esempio:
Library "libSDL2-2.0:0.3000.0" ' const char* SDL_GetPlatform(void) ' Gets the name of the platform. Private Extern SDL_GetPlatform() As String ' int SDL_GetCPUCount(void) ' Returns the number of CPU cores available. Private Extern SDL_GetCPUCount() As Integer ' int SDL_GetCPUCacheLineSize(void) ' Determines the L1 cache line size of the CPU. Private Extern SDL_GetCPUCacheLineSize() As Integer ' SDL_bool SDL_HasRDTSC(void) ' Determines whether the CPU has the RDTSC instruction. Private Extern SDL_HasRDTSC() As Boolean ' SDL_bool SDL_HasAltiVec(void) ' Determines whether the CPU has AltiVec features. Private Extern SDL_HasAltiVec() As Boolean ' SDL_bool SDL_HasMMX(void) ' Determines whether the CPU has MMX features. Private Extern SDL_HasMMX() As Boolean ' SDL_bool SDL_Has3DNow(void) ' Determines whether the CPU has 3DNow! features. Private Extern SDL_Has3DNow() As Boolean ' SDL_bool SDL_HasSSE(void) ' Determines whether the CPU has SSE features. Private Extern SDL_HasSSE() As Boolean ' SDL_bool SDL_HasSSE2(void) ' Determines whether the CPU has SSE2 features. Private Extern SDL_HasSSE2() As Boolean ' SDL_bool SDL_HasSSE3(void) ' Determines whether the CPU has SSE3 features. Private Extern SDL_HasSSE3() As Boolean ' SDL_bool SDL_HasSSE41(void) ' Determines whether the CPU has SSE4.1 features. Private Extern SDL_HasSSE41() As Boolean ' SDL_bool SDL_HasSSE42(void) ' Determines whether the CPU has SSE4.2 features. Private Extern SDL_HasSSE42() As Boolean ' SDL_bool SDL_HasAVX(void) ' Determines whether the CPU has AVX features. Private Extern SDL_HasAVX() As Boolean ' int SDL_GetSystemRAM(void) ' Gets the amount of RAM configured in the system. Private Extern SDL_GetSystemRAM() As Integer Public Sub Main() Print "Sistema operativo in esecuzione: "; SDL_GetPlatform() Print "CPU disponibili: "; SDL_GetCPUCount() Print "Dimensione della linea di cache della CPU: "; SDL_GetCPUCacheLineSize() Print "RDTSC: "; IIf(SDL_HasRDTSC(), "riscontrato", "non riscontrato") Print "AltiVec: "; IIf(SDL_HasAltiVec(), "riscontrato", "non riscontrato") Print "MMX: "; IIf(SDL_HasMMX(), "riscontrato", "non riscontrato") Print "3DNow!: "; IIf(SDL_Has3DNow(), "riscontrato", "non riscontrato") Print "SSE: "; IIf(SDL_HasSSE(), "riscontrato", "non riscontrato") Print "SSE2: "; IIf(SDL_HasSSE2(), "riscontrato", "non riscontrato") Print "SSE3: "; IIf(SDL_HasSSE3(), "riscontrato", "non riscontrato") Print "SSE4.1: "; IIf(SDL_HasSSE41(), "riscontrato", "non riscontrato") Print "SSE4.2: "; IIf(SDL_HasSSE42(), "riscontrato", "non riscontrato") Print "AVX: "; IIf(SDL_HasAVX(), "riscontrato", "non riscontrato") Print "RAM di sistema: "; SDL_GetSystemRAM(); "MB" End
