TIMG2COL

指令示意图

TIMG2COL tile operation

简介

用于类卷积工作负载的图像到列变换。

数学语义

除非另有说明, semantics are defined over the valid region and target-dependent behavior is marked as implementation-defined.

汇编语法

PTO-AS 形式：参见 PTO-AS Specification.

AS Level 1 (SSA)

%dst = pto.timg2col %src : !pto.tile<...> -> !pto.tile<...>

AS Level 2 (DPS)

pto.timg2col ins(%src : !pto.tile_buf<...>) outs(%dst : !pto.tile_buf<...>)

AS Level 1（SSA）

%dst = pto.timg2col %src : !pto.tile<...> -> !pto.tile<...>

AS Level 2（DPS）

pto.timg2col ins(%src : !pto.tile_buf<...>) outs(%dst : !pto.tile_buf<...>)

C++ 内建接口

声明于 include/pto/common/pto_instr.hpp:

PTO_INST RecordEvent TIMG2COL(TileData &dst, ConvTileData &src, uint16_t posM = 0, uint16_t posK = 0,
                              WaitEvents&... events);

约束

  • This instruction is target/implementation-specific. See include/pto/npu/*/TImg2col.hpp for the supported tile types/layouts and config fields.
