C Syntax

#include <xtensa/tie/xt_hifi2.h>

extern void AE_S16M_L_IU(ae_int32x2 d, ae_p16s * a /*inout*/, immediate off);

Description

AE_S16M.L.IU is a 16-bit store 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 {-16,...,14} encoded in the instruction word.

The store instruction writes a 16-bit value to this address taken from the middle of the low entry i of the AE_DR register. p.

This instruction also updates the address register to the virtual address value that was just computed.
