Divides the source operand of type vector_half into two parts in units of 256B, reads one part of the elements, converts them to vector_int32_t type, and writes the result to the destination operand. Multiple rounding modes are supported:

• RINT rounding mode: round half to even.

• ROUND rounding mode: round half up.

• FLOOR rounding mode: round toward negative infinity.

• CEIL rounding mode: round toward positive infinity.

• TRUNC rounding mode: round toward zero.

Taking the asc_half2int32_rd interface as an example:

• asc_half2int32_rd: writes the upper half of the source operand to the destination operand.

• asc_half2int32_rd_v2: writes the lower half of the source operand to the destination operand.
