Common Functions¶

okk_initialize¶

void okk_initialize(): Initialize device before calling GDMA and BDC functions.

void okk_poll()

Synchronize device to make all the previous GDMA and BDC functions done.

Remarks

Before calling this function, the parallel mode is required to be inactive.
After calling this function, it will be blocked until all the previous GDMA and BDC functions are done.

void okk_parallel_start()

Start the parallel mode.

Remarks

Before calling this function, the parallel mode is required to be inactive.
After calling this function, the parallel mode is set active, and the following GDMA kind and BDC kind functions will run paralle.

void okk_parallel_end()

End the parallel mode.

Remarks

Before calling this function, the parallel mode is required to be active.
After calling this function, the parallel mode is set inactive, and the following GDMA kind and BDC kind functions will run serially.

bool okk_is_parallel_state()

Get the flag of the current paralle mode.

Returns: Flag of the current paralle mode, true means active, otherwise, inactive.

unsigned int okk_local_mem_size_per_npu()

Get the size in bytes of local memory in each NPU.

unsigned int okk_l2_sram_size()

Get the size in bytes of L2-SRAM.

unsigned int okk_dtcm_size()

Get the size in bytes of DTCM.

int okk_npu_num()

Get the number of NPUs in each TPU.
