Abstract :
Alternative structures of merged arithmetic are examined for implementing the inner product function. Merged arithmetic dissolves the boundaries between multiplication and addition by synthesizing the entire function directly rather than decomposing the function into discrete multiplies and adds. Fully merged arithmetic eliminates these boundaries completely. A partially merged arithmetic is introduced which retains most of the savings of fully merged arithmetic, while increasing regularity and testability by keeping some of the discrete component structure intact
