Parallel Processor Instruction Set

; Multiple arithmetic example; sr is set to Asize field set to byte; 2 unsigned byte multiplications, subtractions and; shifts preformed using a ‘split’ multiplier

d7 = um d6*d5

|| d5 = d4 - d1 >> -d0

• Byte arithmetic speeds up operations by up to 4 times: speedup is not due to fewer memory accesses but rather due to hardware support for this feature
