Four Other Functions

4.1 DSP Testing

We test G.723 and G.729’s encoding and decoding at different system

speeds to check the rationality of PCB layout.

Operate as follow:

1. Testing data

We need import and verify two standard testing vector file during testing.

The two standard import files are g723in.dat and g729in.dat, and the two

golden results are g723out.dat and g729out.dat.

 G.723 standard test vector file: g723in.dat

 G.723 golden results file: g723out.dat

 G.729 standard test vector file: g729in.dat

 G.729 golden results file: g729out.dat

2. Test method

 G.723 Codec Test

First: Run Palmtool.ext, enter your tested phone’s ip address in
