Conv3DBackpropFilter Tiling Constructor

Function

Creates a single-core Conv3DBackpropFilter tiling object.

Prototype

• Parameterized constructor, which requires the hardware platform information to be passed. You are advised to use this type of constructor to achieve better compatibility.
  • Use PlatformAscendC to pass in information.

    1	explicit Conv3dBpFilterTiling(const platform_ascendc::PlatformAscendC& ascendcPlatform)

  • Use PlatformInfo to pass in information.
    If platform_ascendc::PlatformAscendC fails to be obtained during tiling running, you need to construct the PlatformInfo structure and transparently transmit it to the Conv3dBpFilterTiling constructor.

    1	explicit Conv3dBpFilterTiling(const PlatformInfo& platform)

• Constructor without parameters

  1	Conv3dBpFilterTiling()

• Base class constructor

  Conv3dBpFilterTiling is inherited from the base class Conv3dBpFilterTilingBase. Its constructor is as follows:

  1	Conv3dBpFilterTilingBase()

  1	explicit Conv3dBpFilterTilingBase(const platform_ascendc::PlatformAscendC& ascendcPlatform)

  1	explicit Conv3dBpFilterTilingBase(const PlatformInfo& platform)

struct PlatformInfo {
    platform_ascendc::SocVersion socVersion;
    uint64_t l1Size = 0;
    uint64_t l0CSize = 0;
    uint64_t ubSize = 0;
    uint64_t l0ASize = 0;
    uint64_t l0BSize = 0;
};

platform_ascendc::PlatformAscendC is used to obtain hardware platform information, such as the number of cores on a hardware platform for tiling computation to implement the tiling function on the host. The PlatformAscendC class provides a function for obtaining such platform information.

Different from platform_ascendc::PlatformAscendC, PlatformInfo is used to obtain information specific to a single AI Core, such as the chip version and the memory size provided by each hardware unit in the AI Core.
