This demonstration shows how to implement an audio recorder and player using the C5G board
with the built-in Audio CODEC chip. This demonstration is developed based on Qsys and Eclipse.
Figure 6-14 shows the man-machine interface of this demonstration. Two push-buttons and five
slide switches are used to configure this audio system: SW0 is used to specify recording source to
be Line-in or MIC-In. SW1 is used to enable/disable MIC Boost when the recording source is
MIC-In. SW2, SW3, and SW4 are used to specify recording sample rate as 96K, 48K, 44.1K, 32K,
or 8K. The 7-SEG is used to display Recording/Playing duration with time unit in 1/100 second.
The LED is used to indicate the audio signal strength.
Table 6-3 and Table 6-4 summarize the
usage of Slide switches for configuring the audio recorder and player.
