-
inline void noc_async_read(std::uint64_t src_noc_addr, std::uint32_t dst_local_l1_addr, std::uint32_t size)
-
Initiates an asynchronous read from a specified source node located at NOC coordinates (x,y) at a local address (encoded as a uint64_t using get_noc_addr function). The destination is in L1 memory on the Tensix core executing this function call. Also, see noc_async_read_barrier.
The source node can be either a DRAM bank, a Tensix core or a PCIe controller.
Return value: None
