C5510 DSK ADC
Purpose Configure AIC23 and peripherals to collect data from analog jacks and
output digital data
Library TMS320VC5510 DSP Starter Kit (DSK) (c5510dsk)
Description Configures the AIC23 codec and the TMS320C5510 peripherals to
output a stream of digital data. The block collects this data from the
analog jacks on the C5510 DSP Starter Kit board.

C5510 DSK ADC
Sampling rate
Set the rate at which the analog-to-digital converter samples the
analog input. A higher rate increases the resolution of the data
the ADC outputs.
Word length
Set the number of data bits the ADC creates for each sample.
Increasing the word length increases the accuracy of the data in
each sample. If your model also contains a DAC block, set the
word length in the DAC block to match that of the ADC block.
Samples per frame
Set the number of samples the ADC buffers internally before it
sends the digitized signals, as a frame vector, to the next block
in the model. This value defaults to
frameratedependsonthesamplerateandframesize. Thus,if
you set Sampling Rate to 8 kHz, and Samples per frame to 32,
the resulting frame rate is 250 frames per second (8000/32 = 250).
Inherit sample time
Select whether the block inherits the sample time from the
model base rate or from the Simulink base rate. You can locate
the Simulink base rate in the Solver options in Configuration
Parameters. Selecting Inherit sample time directs the block to use
the specified rate in model configuration. Entering -1 configures
the block to accept the sample rate from the upstream HWI, Task,
or Triggered Task blocks.
64 samples per frame. The

Sampling Rate
Set the rate at which the digital-to-analog converter receives each
data sample. If your model contains an ADC block, set this value
to match the sampling rate of the ADC block.
Word length
Set the number of bits in each data input sample the DAC. If your
model also contains an ADC block, set the word length in the
DAC block to match that of the ADC block. If you do not use an
accurate setting, the DAC cannot convert the data correctly.
Samples per frame
Set the number of samples per data input frame. M atch this value
with the value of the block creating the data frames. This value
