National Instruments 320571-01 用户手册

Enables the DSP board to run.  Use DSP Start
with the DSP Load and DSP Reset VIs after
downloading a custom application.

slot is the board ID number.  slot defaults to 3.

error in (no error) contains the error information from a previous VI.  If an error occurs, it is passed out
error out and no other calls are made.

error out contains the error information for this call.

Extracts a subset of array X of length beginning
at index  and stores it in array Y.

X is a DSP Handle Cluster that indicates the memory buffer on the DSP board that contains the input
signal array X.

index defaults to 0.

length is the length of the output subset.  length defaults to 1.

Y in is a DSP Handle Cluster that indicates the memory buffer on the DSP board that will contain the
subset output array.

Y out is a DSP Handle Cluster that is identical to Y in, but with the subset array already stored in the
memory buffer on the DSP board.

error in (no error) contains the error information from a previous VI.  If an error occurs, it is passed out
error out and no other calls are made.

error out contains the error information for this call.

This VI is particularly useful when performing onboard processing with large arrays, with index different from zero,
or Y in a memory space different from X.  If index is less than zero, then the first element of the subset is the first
element of the input array.
