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

AS Level 1 (SSA)¶

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

AS 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, TileDataTmp &tmp, WaitEvents &... events);

Constraints¶

• Implementation checks (A2A3):
  • Supported element types are uint8_t, int8_t, uint16_t, and int16_t.
  • dst, src, and tmp must use the same element type.
  • In manual mode, source, destination, and temporary storage must not overlap in memory.
• Implementation checks (A5):
  • Supported element types are uint8_t, int8_t, uint16_t, int16_t, uint32_t, and int32_t.
  • dst and src element types must match.
  • src.GetValidRow()/GetValidCol() must match dst.
• Valid region:
  • The op uses dst.GetValidRow() / dst.GetValidCol() as the iteration domain.

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