C Syntax

#include <xtensa/tie/xt_hifi2.h>

extern void AE_S64_I(ae_int64 d, ae_int64 * a, immediate off);

Description

AE_S64.I is a 64-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 {-64,...,56} encoded in the instruction word.

The store instruction writes 64 bits (8 bytes) to memory. The data is taken from the AE_DR register d.
