You mean this is for a mechanical clock? Then telk of a 512K LUT is pointless. You need only 8-bit samples and to shore 90 degrees of the sine function takes 64 bytes. Yes the entire sine wave generators would go into an 80 cent uP. that fits in an 8-pin package.. I've seen examples of this in higher-end battery backup supplies and power inverters. I think I had a desktop computer in about 1980 that I used for word processing mostly. Itwas far less then what now can fit into an 8pin dip and sell for under a buck. I remember it had a 4Mhz 8-bit CPU with about 32MB RAM -- ===== Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
