/* Description : Dot product & addition of byte vector elements
Arguments : Inputs - mult0, mult1
cnst0, cnst1
Outputs - out0, out1
Return Type - unsigned halfword
Details : Unsigned byte elements from mult0 are multiplied with
unsigned byte elements from cnst0 producing a result
twice the size of input i.e. unsigned halfword.
Then this multiplication results of adjacent odd-even elements
are added to the out vector
(2 unsigned halfword results)
