Greeting PJSIP developers.
we have MIPS32 based audicodes SOC that runs on 125 MHz clock.also we have one TI DSP interfaced to this SOC which works with A-law speech and feeds to analog telephones. we have created 4 wave-players and 4 wave writers .we put speech to DSP(instead of file ) in wave writer's file_put_frame(),and get speech from DSP in wave player file_get_frame().we are using master clock
following is our configuration (i .e every 20 ms ). our DSP interface is fast enough(100 MHz static memory controller)
--clock-rate=8000
--null-audio
--ec-tail=0
--dis-codec=GSM
--dis-codec=speex
--dis-codec=G722
with this configuration, 4 wave players alone take 45% CPU and when we connect wave writer ,then sound gets disturbed,and cpu usage become 60%
we have put all CPU performance FAQ optimization techniques but no improvement..
how can i make it work at-least for 4 calls.
will clock thread per call work here .. ??
Please help,
Regards
Kiran Bhosale
