Function Usage

Obtains the version number of the current AI processor architecture.

Prototype

__aicore__ inline void GetArchVersion(uint32_t& coreVersion)

Parameters

Parameter	Input/Output	Description
coreVersion	Output	AI processor architecture version Data type: uint32_t

Parameter

Input/Output

Description

coreVersion

Output

AI processor architecture version

Data type: uint32_t

Returns

None

Constraints

Before calling GetArchVersion, define coreVersion. After GetArchVersion is called, coreVersion changes to the corresponding architecture version.

Due to hardware restrictions, you need to print the converted AI processor architecture version number as a hexadecimal number or directly convert it into a hexadecimal number.

Example

The following example shows how to obtain the AI processor architecture version number by calling GetArchVersion.

    uint32_t coreVersion = 0;// Define the AI processor version.
    AscendC::GetArchVersion(coreVersion);
    AscendC::PRINTF("core version is %x", coreVersion);// Use %x to print it as a hexadecimal number.

Different server models have different architecture version numbers.
