C Syntax

#include <xtensa/tie/xt_hifi2.h>

extern ae_int32x2 AE_SEXT32X2D16_10(ae_int16x4 d0);

Description

AE_SEXT32X2D16.10 promote the two lower 16-bit elements from register d0 and place into the lower 16-bit element of each pair of AE_DR register d. The remaining upper 16-bits of each half are sign extended. This corresponds to ITU intrinsic L_deposit_l.
