Overview

These intrinsics allow inserting or extracting of an individual element into/from a vector.

Inserting can be done either by pushing in a new value at one end of the vector and shifting or replacing a specific element.

Note
An int is converted to a int16 by taking the 16 LSB.
An int is converted to a cint16 by using the 16 LSB as the real part and the 16 MSB as the imaginary part.
There is no int8/uint8 support for these intrincs.

v8int16 shft_elem ( v8int16  vec,
int  n

Insert a new element at the beginning of a vector by shifting the other elements.

These intrinsics shift all elements of a vector up by one element, therefore losing the highest element and insert a new element in the first position and then returns the vector. The following code demonstrates this operation:

DPD considerations

Within the DPD, this intrinsic is used to feed the incoming streams into the corresponding vectors. For example, it might be used like this:

int frac0;
split(get_ss0(), mag_scale, lut_width, idx[0], frac0);
frac = shft_elem(frac, delay2(frac0));
data = shft_elem(data, get_ss1());
v8cint16 shft_elem ( v8cint16  vec,
cint16  n 
)

Insert a new element at the beginning of a vector by shifting the other elements.

These intrinsics shift all elements of a vector up by one element, therefore losing the highest element and insert a new element in the first position and then returns the vector. The following code demonstrates this operation:

for (i=<vector-size>-1; i>0; i--)
{
vec[i]=vec[i-1];
}
vec[0] = n;
Returns
Shifted vector
Parameters
vecVector to be shifted and into which the new value is inserted.
nNew value that will be inserted into the vector.
