Hello Vanima ,

The samples are in HAL (*.c , *.s files) in components directories

#if CORE_SUPPORTS_IVORS
/* The core supports IVOR registers, the kernel requires IVOR4 and IVOR10
and the initialization is performed here.*/
#ifdef __ghs__
asm (
''e_li %r3, %lo(_IVOR4) \t
''
''mtIVOR4 %r3 \t
''
''e_li %r3, %lo(_IVOR10) \t
''
''mtIVOR10 %r3''
);
#else
asm volatile (
''e_li %%r3, _IVOR4@l \t
''
''mtIVOR4 %%r3 \t
''
''e_li %%r3, _IVOR10@l \t
''
''mtIVOR10 %%r3''
: : : 
''memory''
);
#endif
#endif

All CPUs are compatible with the Power Architecture VLE instruction set, which supportssome code size reduction. Best regards Erwan
