Tile Operation Diagram¶

TFMOD tile operation

Introduction¶

Elementwise floor of two tiles.

Math Interpretation¶

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

\[\mathrm{dst}_{i,j} = \mathrm{fmod}(\mathrm{src0}_{i,j}, \mathrm{src1}_{i,j})\]

Assembly Syntax¶

PTO-AS form: see PTO-AS Specification.

Synchronous form:

%dst = tfmod %src0, %src1 : !pto.tile<...>

IR Level 1 (SSA)¶

%dst = pto.tfmod %src0, %src1 : !pto.tile<...>

IR Level 2 (DPS)¶

pto.tfmod ins(%src0, %src1 : !pto.tile_buf<...>) outs(%dst : !pto.tile_buf<...>)

C++ Intrinsic¶

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

template <typename TileDataDst, typename TileDataSrc0, typename TileDataSrc1, typename... WaitEvents>
PTO_INST RecordEvent TFMOD(TileDataDst &dst, TileDataSrc0 &src0, TileDataSrc1 &src1, WaitEvents&... events);

Constraints¶

The op iterates over dst.GetValidRow() / dst.GetValidCol().
Division-by-zero behavior is target-defined; the CPU simulator asserts in debug builds.

Examples¶

#include <pto/pto-inst.hpp>

using namespace pto;

void example() {
  using TileT = Tile<TileType::Vec, int32_t, 16, 16>;
  TileT out, a, b;
  TFMOD(out, a, b);
}

ASM Form Examples¶

Auto Mode¶

# Auto mode: compiler/runtime-managed placement and scheduling.
%dst = pto.tfmod %src0, %src1 : !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.tfmod %src0, %src1 : !pto.tile<...>

PTO Assembly Form¶

%dst = tfmod %src0, %src1 : !pto.tile<...>
# IR Level 2 (DPS)
pto.tfmod ins(%src0, %src1 : !pto.tile_buf<...>) outs(%dst : !pto.tile_buf<...>)
