The Delay block outputs a delayed version of the input signal. The input is delayed by the number of samples reflected in the Cur numeric text box. The top drop-down menu labeled Max represents the largest amount of delay that could be applied to the input signal. If you select a new Max value in the drop-down menu, you will be forced to recompile.

The maximum delay available for a particular delay block depends on the total available system data RAM, which is specified in the DSP processor datasheet. Setting the Max control's value, allocates memory on the DSP, reserving that memory for use by this particular block only, and reducing the available memory for all other delay blocks in the design. This is a compiler directive and modifies the assembly code, so any time you change the Max setting you must recompile and download the program. The maximum delay value range is limited to the remaining unallocated memory of the RAM.

Configurable Parameters

GUI Parameter NameDefault ValueRangeFunction Description
IsSampleTrueTrue/FalseAllows the Max and Cur delay controls either in Samples or milliseconds
MaxDelay1 1 to 1500 (Depends on Size of the Memory available) This control specifies the maximum delay supported for the current instance in samples (32-bit word). Change in this value requires a re-compilation
CurDelay1 1 to MaxDelayCurrent Daly Value
NumChannels120Numer of input and output channels.Chnage in this value requires re-compilation
