TXORS¶

Tile Operation Diagram¶

Introduction¶

Elementwise bitwise XOR of a tile and a scalar.

Math Interpretation¶

For each element (i, j) in the valid region:

Assembly Syntax¶

PTO-AS form: see PTO-AS Specification.

Synchronous form:

%dst = txors %src, %scalar : !pto.tile<...>, i32

IR Level 1 (SSA)¶

%dst = pto.txors %src, %scalar : (!pto.tile<...>, dtype) -> !pto.tile<...>

IR Level 2 (DPS)¶

pto.txors ins(%src, %scalar : !pto.tile_buf<...>, dtype) outs(%dst : !pto.tile_buf<...>)

C++ Intrinsic¶

Declared in include/pto/common/pto_instr.hpp:

template <typename TileDataDst, typename TileDataSrc, typename TileDataTmp, typename... WaitEvents>
PTO_INST RecordEvent TXORS(TileDataDst& dst, TileDataSrc& src0, typename TileDataSrc::DType scalar, typename TileDataTmp &tmp, WaitEvents&... events);

Constraints¶

• Intended for integral element types.
• The op iterates over dst.GetValidRow() / dst.GetValidCol().
• Individual temporary space is required by A3 for calculation, while not used by A5.
• Setting the source Tile and destination Tile to the same memory is Unsupported.
• For A3, do not set temporary space to the same memory as source Tile or destination Tile.

Examples¶

#include <pto/pto-inst.hpp>

using namespace pto;

void example() {
  using TileDst = Tile<TileType::Vec, uint32_t, 16, 16>;
  using TileSrc = Tile<TileType::Vec, uint32_t, 16, 16>;
  using TileTmp = Tile<TileType::Vec, uint32_t, 16, 16>;
  TileDst dst;
  TileSrc src;
  TileTmp tmp;
  TXORS(dst, src, 0x1u, tmp);
}

ASM Form Examples¶

Auto Mode¶

# Auto mode: compiler/runtime-managed placement and scheduling.
%dst = pto.txors %src, %scalar : (!pto.tile<...>, dtype) -> !pto.tile<...>

Manual Mode¶

# Manual mode: bind resources explicitly before issuing the instruction.
# Optional for tile operands:
# pto.tassign %arg0, @tile(0x1000)
# pto.tassign %arg1, @tile(0x2000)
%dst = pto.txors %src, %scalar : (!pto.tile<...>, dtype) -> !pto.tile<...>

PTO Assembly Form¶

%dst = txors %src, %scalar : !pto.tile<...>, i32
# IR Level 2 (DPS)
pto.txors ins(%src, %scalar : !pto.tile_buf<...>, dtype) outs(%dst : !pto.tile_buf<...>)
