=================
|
||
|
||
生成等差序列，逐元素写入输出：
|
||
|
||
.. math::
|
||
|
||
output_i = start + i \times delta,\quad i = 0, 1, \dots, \text{length} - 1
|
||
|
||
输入：
|
||
- **start** - 序列起始值。
|
||
- **delta** - 公差。
|
||
- **length** - 序列长度。
|
||
- **core_mask（可选）** - 核掩码（仅适用于共享存储版本）。
|
||
|
||
输出：
|
||
- **output** - 输出数据地址。
|
||
|
||
支持平台：
|
||
``FT78NE``
|
||
``MT7004``
|
||
|
||
.. note::
|
||
- FT78NE 支持 int8, int16, int32, fp32, fp64。
|
||
- MT7004 支持 fp16, fp32, int16, int32（如需 fp16，请使用相应 fp16 实现）。
