C Syntax

#include <xtensa/tie/xt_hifi2.h>

extern xtbool2 AE_EQ32(ae_int32x2 d0, ae_int32x2 d1);

Description

AE_EQ32 is an element-wise equality on two AE_DR registers d0 and d1; results go to a pair bhl of adjacent Boolean registers. bhl[0] is set if and only if the low element of d0 is equal to the low element of d1. Similarly, bhl[1] is set if and only if the high element of the first input AE_DR register is equal to the high element of the second input AE_DR register.
