Assembler Syntax

AE_S32X2.I aed0..15(ae_ls_v), a0..15(ars), -64..56

C Syntax

#include <xtensa/tie/xt_hifi2.h>

extern void AE_S32X2_I(ae_int32x2 d, ae_int32x2 * a, immediate off);

Description

AE_S32X2.I stores two 32-bit values to memory from the AE_DR register. It forms a virtual address by adding the contents of the address register and an immediate value within the range {-64,...,56} encoded in the instruction word.

The store instruction writes two, 32-bit values to memory. The data is taken from the AE_DR register d.
