/*! \page g711_page A-law and mu-law handling
|
||||
Lookup tables for A-law and u-law look attractive, until you consider the impact
|
||||
on the CPU cache. If it causes a substantial area of your processor cache to get
|
||||
hit too often, cache sloshing will severely slow things down. The main reason
|
||||
these routines are slow in C, is the lack of direct access to the CPU's "find
|
||||
the first 1" instruction. A little in-line assembler fixes that, and the
|
||||
conversion routines can be faster than lookup tables, in most real world usage.
|
||||
A "find the first 1" instruction is available on most modern CPUs, and is a
|
||||
much underused feature.
|
||||
|
||||
If an assembly language method of bit searching is not available, these routines
|
||||
revert to a method that can be a little slow, so the cache thrashing might not
|
||||
seem so bad :(
|
||||
|
||||
Feel free to submit patches to add fast "find the first 1" support for your own
|
||||
favourite processor.
|
||||
|
||||
Look up tables are used for transcoding between A-law and u-law, since it is
|
||||
difficult to achieve the precise transcoding procedure laid down in the G.711
|
||||
specification by other means.

The G.722 module is a bit exact implementation of the ITU G.722 specification for all three

specified bit rates - 64000bps, 56000bps and 48000bps. It passes the ITU tests.
|
||||
|
||||
To allow fast and flexible interworking with narrow band telephony, the encoder and decoder
|
||||
support an option for the linear audio to be an 8k samples/second stream. In this mode the
|
||||
codec is considerably faster, and still fully compatible with wideband terminals using G.722.

It supports:

- 16 kbps, 24kbps, 32kbps, and 40kbps operation.

- Tandem adjustment, for interworking with A-law and u-law.

- Annex A support, for use in environments not using A-law or u-law.

It passes the ITU tests.
