| -- This package contains generic procedures for vector operations on arrays. |
| -- If the arguments are aligned on word boundaries and the word size is a |
| -- multiple M of the element size, the operations will be done M elements |
| -- at a time using vector operations on a word. |
| |
| -- All routines assume argument arrays have the same length, and arguments |
| -- with mode "in" do not alias arguments with mode "out" or "in out". |
| -- If the number N of elements to be processed is not a multiple of M |
| -- the final N rem M elements will be processed one item at a time. |
