A pipeline stage computes a vector-valued function of a vector of bits. One may consider the coordinate functions one by one, The delay for the function as a whole is the maximum of the coordinate function delays.

Often the coordinate functions will depend on only a subset
of the input vector components. If and
then the size of is the *logical radius* of the *i*th
component of *f*. Since the delay associated with is a
function of the radius, balancing the radii of the component
functions is a guideline in choosing the pipeline decomposition
of a computational task.
