D.4 12xDSP Audio Transcode Voip Channel Demo
Application
The following is the additional information available in
README_max_channel_tests.txt
file at
/opt/octasic/application/sample/octvoc/12dsp_audio_transcode_net_a
pi
location.
D.4.1 Introduction
12dsp_audio_transcode_net_api -
sets up to 400 IP to IP channels (800 IP end points)
per DSP. The main purpose of this software is to load the DSPs with maximum IP to IP channels
so that the test is set in pairs of physical DSPs.
This software code assumes that there are 12 DSPs available and that the code is running on
the Xeon server host with RHEL, though it should run on other hosts.
NOTE: Main change is to change the data structures to large arrays.
Some functions are copied from existing sample files and are named as MyXXXXXXX, whereas
XXXXXX
is the original function name.
DSP IP Addresses are controlled by these #defines
#define DSP_IP_BASE 0xC0A84C00
#define DSP_IP_START 201
