32 | -- This package contains generic procedures for vector operations on arrays. |
| 33 | -- If the arguments are aligned on word boundaries and the word size is a | |
| 34 | -- multiple M of the element size, the operations will be done M elements | |
| 35 | -- at a time using vector operations on a word. | |
| cacbc350 | 36 | |
| fbf5a39b AC |
37 | -- All routines assume argument arrays have the same length, and arguments |
| 38 | -- with mode "in" do not alias arguments with mode "out" or "in out". | |
| 39 | -- If the number N of elements to be processed is not a multiple of M | |
| 40 | -- the final N rem M elements will be processed one item at a time. | |
