TFMOD

Tile Operation Diagram

Introduction

Elementwise floor of two tiles.

Math Interpretation

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

$${\mathrm{d}\mathrm{s}\mathrm{t}}_{i,j}=\mathrm{f}\mathrm{m}\mathrm{o}\mathrm{d}({\mathrm{s}\mathrm{r}\mathrm{c}0}_{i,j},{\mathrm{s}\mathrm{r}\mathrm{c}1}_{i,j})$$

Assembly Syntax

Synchronous form:

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

AS Level 1 (SSA)

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

AS 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: resources must be bound 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<...>
# AS Level 2 (DPS)
pto.tfmod ins(%src0, %src1 : !pto.tile_buf<...>) outs(%dst : !pto.tile_buf<...>)
