noc_semaphore_inc

template<bool posted = false>
void noc_semaphore_inc(uint64_t addr, uint32_t incr, uint8_t noc_id = noc_index, uint8_t vc = NOC_UNICAST_WRITE_VC)

The Tensix core executing this function call initiates an atomic increment (with 32-bit wrap) of a remote Tensix core L1 memory address. This L1 memory address is used as a semaphore of size 4 Bytes, as a synchronization mechanism. Refer to <arch>/noc/noc.h for the documentation of noc_atomic_increment.

Return value: None
