'C62x Instruction Set (by category)Aritmetica di saturazioneSe 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 un evento particolarmente frequente in applicazioni multimediali (ad esempio nei valori di colore dei pixel) e laritmetica di saturazione serve appunto a questo.

This foil doesnt need much introduction. The C67x includes all the C62x instructions along with these additional instructions.

Those that end in SP are for single-precision floating-point; those in DP are for double-precision floating-point.

(I dont discuss this, but we dont really have material on the timers - these are easy enough to figure out on their own from the specs). The main point here is to simply say that each of these can exist on the C6x and a one sentence description of their capability. I sometimes note that the EMIF is considered a peripheral - outside of the core CPU. Depending on the exact device (C6201 for example), the peripheral mix may change. Dont get into too much detail on any one peripheral - unless the question is simple/quick to answer - again, we will have time to explore each of these later.Each of these peripherals has a module dedicated to them.

Many people ask - so when you say clock cycle what do you mean? This is the def'n. It is the machine rate of the processor and this explains how we get the number. But depending on your system - you can choose any number you want by using a different CLKIN and PLL option.
