Tile Operation Diagram

TAXPY tile operation

Introduction

AXPY-style fused update: multiply a tile by a scalar and accumulate into the destination tile.

Math Interpretation

Semantics are instruction-specific. Unless stated otherwise, behavior is defined over the destination valid region.

Assembly Syntax

PTO-AS form: see docs/assembly/PTO-AS.md.

IR Level 1 (SSA)

%dst = pto.taxpy ...

IR Level 2 (DPS)

pto.taxpy ins(...) outs(%dst : !pto.tile_buf<...>)

C++ Intrinsic

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

Constraints

Refer to backend-specific legality checks for data type/layout/location/shape constraints.

Examples

See related instruction pages in docs/isa/ for concrete Auto/Manual usage patterns.
