SET_QUANT_VECTOR¶

Introduction¶

Set the vector quantization parameter for subsequent TPUSH operations by configuring the hardware FPC register from a Scaling-type tile's address. The tile address is converted to the quantization parameter address format and written to the hardware quantization configuration.

C++ Intrinsic¶

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

template <typename FpTileData, typename... WaitEvents>
PTO_INST RecordEvent SET_QUANT_VECTOR(FpTileData &fpTile, WaitEvents &...events);

Constraints¶

• FpTileData::Loc must be TileType::Scaling. Only Scaling-type tiles are supported as input.
• This instruction must be called before the TPUSH instruction that consumes this configuration.
• The tile address encoding into the hardware FPC register is implementation-defined.

Examples¶

#include <pto/pto-inst.hpp>

using namespace pto;

template <typename T>
AICORE void example_set_quant_vector()
{
    using ScalingTile = Tile<TileType::Scaling, T, 1, 128, BLayout::RowMajor, 1, 128>;
    ScalingTile fpTile;
    TASSIGN(fpTile, 0x0);

    SET_QUANT_VECTOR(fpTile);
}

ASM Form Examples¶

The current public assembly reference does not define a stable PTO-AS spelling for SET_QUANT_VECTOR. Use the C++ intrinsic form for quantization configuration.
