TNOT¶

指令示意图¶

简介¶

Tile 的逐元素按位取反。

数学语义¶

对每个元素 (i, j) 在有效区域内：

汇编语法¶

PTO-AS 形式：参见 PTO-AS Specification.

同步形式：

%dst = tnot %src : !pto.tile<...>

AS Level 1 (SSA)¶

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

AS Level 2 (DPS)¶

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

AS Level 1（SSA）¶

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

AS Level 2（DPS）¶

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

C++ 内建接口¶

声明于 include/pto/common/pto_instr.hpp:

template <typename TileDataDst, typename TileDataSrc, typename... WaitEvents>
PTO_INST RecordEvent TNOT(TileDataDst &dst, TileDataSrc &src, WaitEvents &... events);

约束¶

• 实现检查 (A2A3):
  • TileData::DType must be one of: int16_t, uint16_t.
  • Tile 布局 must be row-major (TileData::isRowMajor).
  • Tile location must be vector (TileData::Loc == TileType::Vec).
  • Static valid bounds: TileData::ValidRow <= TileData::Rows and TileData::ValidCol <= TileData::Cols.
  • Runtime: src and dst tiles should have the same validRow/validCol.
• 实现检查 (A5):
  • TileData::DType must be one of: uint32_t, int32_t, uint16_t, int16_t, uint8_t, int8_t.
  • Tile 布局 must be row-major (TileData::isRowMajor).
  • Tile location must be vector (TileData::Loc == TileType::Vec).
  • Static valid bounds: TileData::ValidRow <= TileData::Rows and TileData::ValidCol <= TileData::Cols.
  • Runtime: src and dst tiles should have the same validRow/validCol.
• 有效区域:
  • The op uses dst.GetValidRow() / dst.GetValidCol() as the iteration domain; src/dst are assumed to be compatible (not validated by explicit runtime checks in this op).

示例¶

#include <pto/pto-inst.hpp>

using namespace pto;

void example() {
  using TileT = Tile<TileType::Vec, uint16_t, 16, 16>;
  TileT x, out;
  TNOT(out, x);
}
