Hey,

Is there any method to obtain the DSP utilization in beagle board,
similar to 'top' or 'sysstat' to get information of CPU usage?

Thanks.

If you are using TI’s codec engine/dsplink mechanism there is an engine api can tell you average cpu load.Engine_getCpuLoad(). Check out the html documentation within the codec engine here http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/ce/2_25_02_11/exports/codec_engine_2_25_02_11/docs/html/group___c_o_d_e_c_e_n_g_i_n_e.html. If not then it gets a bit tricky unless you are developing the dsp side software too.

If you use tidspbridge, you can use dsp-load from dsp-tools:

and in both cases you need some SW that will actually use the DSP,
its not like linux schedules tasks on the DSP by default..
