TEXTRACT_FP¶

Tile Operation Diagram¶

TEXTRACT_FP tile operation

Introduction¶

Extract a sub-tile from a source tile, while also providing an fp (scaling) tile used for vector quantization parameters (target/implementation-defined).

C++ Intrinsic¶

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

PTO_INST RecordEvent TEXTRACT_FP(DstTileData &dst, SrcTileData &src, FpTileData &fp,
                            uint16_t indexRow, uint16_t indexCol, WaitEvents&... events);

Math Interpretation¶

Unless otherwise specified, semantics are defined over the valid region and target-dependent behavior is marked as implementation-defined.

Assembly Syntax¶

PTO-AS form: see PTO-AS Specification.

IR Level 1 (SSA)¶

%dst = pto.textract_fp %src, %idxrow, %idxcol : (!pto.tile<...>, dtype, dtype) -> !pto.tile<...>

IR Level 2 (DPS)¶

pto.textract_fp ins(%src, %idxrow, %idxcol : !pto.tile_buf<...>, dtype, dtype) outs(%dst : !pto.tile_buf<...>)

Constraints¶

Type/layout/location/shape legality is backend-dependent; treat implementation-specific notes as normative for that backend.

Examples¶

See related examples in docs/isa/ and docs/coding/tutorials/.

ASM Form Examples¶

Auto Mode¶

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

PTO Assembly Form¶

%dst = pto.textract_fp %src, %idxrow, %idxcol : (!pto.tile<...>, dtype, dtype) -> !pto.tile<...>
# IR Level 2 (DPS)
pto.textract_fp ins(%src, %idxrow, %idxcol : !pto.tile_buf<...>, dtype, dtype) outs(%dst : !pto.tile_buf<...>)
