From this overview it is clear there are better choices for the random function in Tiny Core. Even the Xorshift-16 generator is a good choice for some applications (like a Blinky).
|Xorshift||126||4||0.323||– 4||primary choice, normal quality|
|CRC32||104||4||0.610||– 1||secondary choice, better quality|
|Xorshift-16||34||2||0.044||low||use for ’13, maybe ‘2n|
The current plan is to use Xorshift as the default generator. Of the generators evaluated, it isn’t the smallest nor the fastest nor the best quality. It is small, fast, andgood quality so it is a very nice compromise.
The CRC32 generator will be an available option as a better quality smaller generator.
The JKISS32 generator will be an available option as a very high quality generator on all but the processors with the least memory (probably only excluding the ATtiny13).
The Xorshift-16 generator will be the default for the ATtiny13 processor and possibly the ATtiny25 and ATtiny24 processors.
