C Syntax

#include <xtensa/tie/xt_hifi2.h>

extern ae_f32x2 AE_CVT32X2F16_32(ae_f16x4 d0);

Description

AE_CVT32X2F16.32 promote the two higher 16-bit elements from register d0 and place into the higher 16-bit element of each pair of AE_DR register d. The remaining lower 16-bits of each half of register d are filled with 0. This corresponds to ITU intrinsic L_deposit_h.
