+/* Description : Dot product & addition of byte vector elements
+ Arguments : Inputs - mult0, mult1

+ 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)
