Mojo struct
DecodeSM100PVSS
struct DecodeSM100PVSS[operand_type: DType, accum_type: DType, *, config: MLA_SM100_Decode_Config]
Tensor accumulator for the PV MMA with both P and V operands in SMEM.
Parameters
- operand_type (
DType): Element type of the P and V operands in SMEM. - accum_type (
DType): Accumulator dtype used for the PV MMA result in TMEM. - config (
MLA_SM100_Decode_Config): Decode config supplying MMA tile dimensions and swizzle modes.
