-- In the future this package may also define operations such as element-wise
|
|
-- addition, subtraction, multiplication, minimum and maximum of vector-sized
|
|
-- packed arrays of Unsigned_8, Unsigned_16 and Unsigned_32 values. These
|
|
-- operations could be implemented as system intrinsics on platforms with
|
|
-- direct processor support for them.
