在SPI 平台优化好的G.711代码,保证好用

=====================================================================
G.711 Demo Example
=====================================================================

Description
-----------

This directory contains code for a basic G.711 encoder.

g711_decode_c.c:	reference C implementation
g711_decode.sc:		StreamC implementation;
			described in detail as tutorial example in "RapiDev User's Guide"
			(for --target host and --target tcshost only!)
g711.sc			StreamC implementation
			(for all targets, including Stream Processor hardware)
spi_configure.c		DSP MIPS configuration

Building
--------

In a bash shell, type:

$ ./build.sh

This builds g711 for all compilation targets: host, tcshost, and device. 
It builds both SP16 and SP8 versions.

Running
-------

In a Cygwin bash shell, type:

$ ./g711.host

This runs the FFD (--target host) version of g711, which should print the message:

Success!

To run the tcshost version of g711, type:

$  ./g711.tcshost

To run the tcs version of g711 under TCS, type:

$ start_tcs_mips -i g711.device.out		# run SP16 version under TCS
$ start_tcs_mips -a sp8 -i g711.device.sp8.out	# run SP8 version under TCS

Type <Ctrl-C> to interrupt TCS after the G.711 task terminates.

g711.device.out is also suitable for execution on Stream Processor hardware.
Download it to a Storm-1 Development Kit board, then log in to the board and type

$ spi_load_dsp_mips -t -x g711.device.out

You can also download and run g711.device.out directly
from the Run Program webpage on the board.
