passend, die Keramik-Cs stimmen normalerweise auch noch. Fehler dort sind zu 99% nur eine taube ECC85 oder komplett fehlende Betriebsspannung (Siebwiderstände, Tastensatzkontakte usw.). Ansonsten hat es Peter Dannegger ja schon geschrieben: keine Spulenkerne verdrehen, keine Trimmer verstellen.

Ich bin kein ECC-Freak, aber soweit ich weiß gibt es diverse Klassen bei den CRCs. Manche davon können auch zur Fehlerkorrektur verwendet werden, was vor allem von der Blocklänge abhängt. Man könnte sich an Henning

danke, hab aber eben noch etwas gefunden. und zwar hat der M32C85 ein XY-Conversion Register. das ist eigentlich schon eine matrix mit der man (so denke ich zumindest) dies sehr einfach erschlagen kann, da man, nachdem man die 8 byte in entsprechende register geschrieben

Naja, auf CDs/DVDs und Festplatten sowie in ECC-RAM wird nie CRC verwendet und das Partitätsbit ist da auch längst ausgestorben, weil damit bestenfalls abgeschaltet werden kann - mit dem ECC werden aber alle 1-Bit-Fehler korrigiert und meist sind 2-Bit-Fehler zumindest erkennbar. Deshalb verwende ich im PC ECC-RAM, denn bevor das wirklich ausfällt, wird man schon durch entsprechende Logfile-Einträge gewarnt.
. Ich habe deshalb mal die folgenden 2 Beispiele in C gecodet. Two simple short Codes for ECC: =============================== Code [8, 4, 4, 2]: ------------------ 00000000 = 0 00001111 = 15 00110011 = 51 00111100 = 60 01010101 = 85 01011010 = 90 01100110 = 102 01101001
stimmt so nicht, denn bei der ECC-Kodierung wird ein Nutzdatenwort in ein längeres ECC-Codewort übersetzt und dieses übersetzte Codewort kann man i. Allg. nicht in Nutz- und Korrektur-Bits zerlegen. Insofern sind ECC und CRC oder md5sum
