Assembler Syntax

AE_L32.I aed0..15(ae_ls_v), a0..15(ars), -32..28

C Syntax

#include <xtensa/tie/xt_hifi2.h>

extern ae_int32x2 AE_L32_I(const ae_int32 * a, immediate off);

Description

AE_L32.I is a 32-bit load from memory. into the AE_DR register. It forms a virtual address by adding the contents of the address register and an immediate value within the range {-32,...,28} encoded in the instruction word.

The load instruction reads 32 bits (4 bytes) from memory and replicates the data into each of the two halves of the AE_DR register d.
