enum io_profiling_option
{
io_total_stream_running_to_idle_cycles,
io_stream_start_to_bytes_transferred_cycles,
io_stream_start_difference_cycles,
io_stream_running_event_count
};
The io_profiling_option
contains the
enumerated options for performance profiling using PLIO and GMIO objects. The
io_total_stream_running_to_idle_cycles
option
represents the total accumulated clock cycles in between the stream running event
and the stream idle event of the corresponding stream port in the interface tile.
This option can be used to profile platform I/O bandwidth.
The io_stream_start_to_bytes_transferred_cycles
option represents the
clock cycles in between the first stream running event to the event that the
specified number of bytes are transferred through the stream port in the interface
tile. This option can be used to profile graph throughput.
The io_stream_start_difference_cycles
option represents the clock cycles
elapsed between the first stream running events of the two platform I/O objects.
This option can be used to profile graph latency.
The io_stream_running_event_count
option represents the number of stream running events. This option can be used to
profile the graph throughput during a period of time for streaming applications.
