'C62xInstruction Set (by category) Aritmetica di saturazione Se utilizzo la classica aritmetica di arrotondamento quando, ad esempio in un procedimento di incremento di colore, giungo al limite di rappresentazione di un dato un ulteriore incremento determina un overflow con il numero che raggiunge erroneamente il limite opposto. Quando io sommo invece ad esempio due valori a 32 bit che raggiungono un valore che eccede i limiti di rappresentazione avrei semplicemente bisogno di indicare che ho raggiunto il valore massimo rappresentabile. Questo è un evento particolarmente frequente in applicazioni multimediali (ad esempio nei valori di colore dei pixel) e l’aritmetica di saturazione serve appunto a questo.
