/* Description : Dot product of byte vector elements
* Arguments : Inputs - mult0, mult1, cnst0, cnst1
* Outputs - out0, out1
* Return Type - as per RTYPE
* Details : Signed byte elements from 'mult0' are multiplied with
* signed byte elements from 'cnst0' producing a result
* twice the size of input i.e. signed halfword.
* The multiplication result of adjacent odd-even elements
* are added together and written to the 'out0' vector
