TNEG¶

指令示意图¶

简介¶

Tile 的逐元素取负。

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 = tneg %src : !pto.tile<...>

AS Level 1 (SSA)¶

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

AS Level 2 (DPS)¶

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

AS Level 1（SSA）¶

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

AS Level 2（DPS）¶

pto.tneg 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 TNEG(TileDataDst &dst, TileDataSrc &src, WaitEvents &... events);

约束¶

• The op iterates over dst.GetValidRow() / dst.GetValidCol().

示例¶

#include <pto/pto-inst.hpp>

using namespace pto;

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