DSP Readback (Complex)

Click here to return to the Basic DSP page

The DSP Readback(complex) block lets you read complex values back from the DSP at any point in your schematic design.

The number displayed onscreen is the data value sent back from the DSP considering all the blocks to the left of the Readback block. Every time you click Read, this value will be updated with the latest from the DSP. By displaying the output value from any block, in any format desired, Readback is used chiefly for debugging, and probably will prove very handy.Values can be read back in either hex or decimal. For the latter, you must specify what format you want the number to be displayed in.

Input Pins

NameFormat [int/dec] - [control/audio]Function Description
Pin 0: Input Signal Complex Input complex signal

Output Pins

NameFormat [int/dec] - [control/audio]Function Description
Pin 0: Output Signal Complex Output complex signal. Same as Input complex signal.

GUI Controls

GUI Control NameDefault ValueRangeFunction Description
Real NA 0 - (Depends on the format select)This control gives the read real value
ImaginaryNA 0 - (Depends on the format select)This control gives the read imaginary value
format8.24 1.31 to 32.0 This control decides the range

Grow and Add Algorithm

The module currently does not support grow functionality and Add Algorithm is supported. Supported to Multiple Instances.
