Mojo struct
OutputRegisterBufferRDNA
struct OutputRegisterBufferRDNA[dtype: DType, num_m_mmas: Int, num_n_mmas: Int]
Output accumulator register buffer. Layout is (num_n_mmas * num_m_mmas, RDNA_CD_FRAG_SIZE) row_major: one row per MMA tile, one column per per-lane C/D register.
Parameters
- dtype (
DType): Element type of the output accumulator registers. - num_m_mmas (
Int): Number of MMA tiles along the M (query) axis. - num_n_mmas (
Int): Number of MMA tiles along the N (key) axis.
Fields
- reg_tile (
OutputRegisterBufferRDNA[dtype, num_m_mmas, num_n_mmas].RegisterTileType):
