    Overview DMA-8x8 system, if you notice that your signal has been clipped before it is outputted and transmitted to the digital-to-analog converter, you may close it off immediately at the output section to correct the situation. By using the fixed-point sys- tem, you have to search each processing module to find the clipping source.

    Workflow DMA-8x8 5. General Workflow The following steps outline a typical DSP Software workflow. 5.1. Configure DMA8X8 The natural first step when working with DSP Software is to configure the software to match the con- nected hardware. The DMA8X8 supports eight channels of input and eight channels output. Inputs may be analog signal or the internal Signal Generator;...

Compressor (COMP) The compressor is used to reduce the dynamic range of the signal higher than the threshold set by the users, and to maintain the dynamic range of the signal lower than the threshold. The compressor has the follow- ing control parameters: Fig 13 Compressor module Threshold: When the signal level is higher than the threshold, the compressor/limiter begins to re-...
  • Page 18 Workflow DMA-8X8 5.3.4. Auto Gain Control (AGC) Auto gain control (AGC) is an exception of compressor. Its threshold is set at a very low level with middle-to-slow starting time, long release time and low ratio. The purpose is to improve the signal uncertain level to a target level, while maintaining the dynamic range at the same time.

Fig. 15 EQ Control moudule High & Low Shelf Filter: It is also called shelf filter. High shelf filter means that the gain enhances or attenuates the frequencies above the set frequency.
  • Page 20 Workflow DMA-8X8 Fig.16 Feedback Inhibition module After the buzzer output, the filter may be locked up to prevent any change during the performance period. The filter settings can be copied to a dedicated notching filter module (such as equalizer). Eight filters are set as auto filters in an automatic cycle.

    Workflow DMA-8X8 Fig. 17 Application Noise Suppression module There is only an echo cancellation module in DSP Controller. Multichannel mixers are preset to real- ize multichannel participating noise cancellation as shown in the figure 17. Suppression level: There are totally five levels from 6 dB to 30 dB for selecting. dB here refers to the decibel of suppression noise reduction.
  • Page 25 Workflow DMA-8x8 Type: There are three types of filters, including Bessel, Butterworth and Linkwitz-Riley. Butterworth has the flattest passband. Slope: It refers to attenuation values of the transition zone of filters. There are totally 8 attenuation values, including 6, 12, 18, 24, 30, 36, 42 and 48dB/Oct. For example, 24dB/Oct indicates that the attenuation range is 24dB for each octave difference existed in frequency in the transition zone.
  • Page 26 Workflow DMA-8X8 Fig.20 Output Limiter module The limiter only provides two parameters: Threshold and Release Time. In terms of signal process- ing, occasional clipping will be solved via limiter, while the signal level shall be attenuated in terms of frequent clip- ping.

    APP User DMA-8x8 9.2. Control Protocol Because of historical reasons, the latest control protocol adopts variable-length and is fully compati- ble with old fixed-length control protocols. In protocols, the fourth byte is used to distinguish versions. 0- indicates V1 version (previous versions) and 1- indicates V2 version (current protocol version). The difference between V1 and V2 is V1 may control all processing module parameters, but one command can only control one parameter.
