Arguments : Inputs - in0, in1, in2, in3,
Outputs - out0, out1
Return Type - as per RTYPE
Details : Each byte element from 'in0' vector is added with each byte
element from 'in1' vector. The addition of the elements plus 1
(for rounding) is done unsigned with full precision,
i.e. the result has one extra bit. Unsigned division by 2
(or logical shift right by one bit) is performed before writing
the result to vector 'out0'
Similar for the pair of 'in2' and 'in3'
