TSETHF32MODE

指令示意图

TSETHF32MODE tile operation

简介

设置 HF32 变换模式（实现定义）。

数学语义

No direct tensor arithmetic is produced by this instruction. It updates target mode state used by subsequent instructions.

汇编语法

PTO-AS 形式：参见 docs/assembly/PTO-AS.md.

Schematic form:

tsethf32mode {enable = true, mode = ...}

AS Level 1（SSA）

pto.tsethf32mode {enable = true, mode = ...}

AS Level 2（DPS）

pto.tsethf32mode ins({enable = true, mode = ...}) outs()

C++ 内建接口

声明于 include/pto/common/pto_instr.hpp:

template <bool isEnable, RoundMode hf32TransMode = RoundMode::CAST_ROUND, typename... WaitEvents>
PTO_INST RecordEvent TSETHF32MODE(WaitEvents &... events);

约束

  • Available only when the corresponding backend capability macro is enabled.
  • Exact mode values and hardware behavior are target-defined.
  • This instruction has control-state side effects and should be ordered appropriately relative to dependent compute instructions.

示例

#include <pto/pto-inst.hpp>
using namespace pto;

void example_enable_hf32() {
  TSETHF32MODE<true, RoundMode::CAST_ROUND>();
}
