Making your life easier is good. > I'm planning to use MAXIM's signal generator or motorola fast microcontroller, > maybe dallas 80Cxxx or atmel's AT90Sxxx. Atmel has some very capable MCU's. Although they still might not be fast enough. With an output speed of 1MHz you will still only be able to execute 10 instructions per output cycle on an AT90@xxxx running at 10MHz ( 1 instruction per clock cycle = 10 million instructions per second at 10MHz ). > Day by day I'm thinking about "great" Intel's microprocessors efficiency... > and I'm really considering switchng to MOTOROLA for good :) I'm not sure what you mean by this. > I don't want to piss off anyoune, but I think that those guys who tols me so > many bad things abut ->->>GNU<<-<- assembler, should read assembly-howto... > I was not talking abut ->NASM<-. Never mind... peace! ATARI RULZ! :] I don't think they were trying to say that GNU or any particular assembler is bad, but just not really necessary when your target CPU is running at hundreds of megahertz and is running a high level operating system like Linux. If your target is an MCU and you have very tight timing requirements you most likely need to use assembler. In fact, if you use the Atmel AVR MCU's you can use avr-gcc to write the code and use as much inline assembly as you want. There is an email list for avr-gcc that would be much more helpful for your project than this list. > Once again thanks for all help and sugestions! > I'll call You when device ready... > > TANKS! > CeDeROM/KSZAK > > _______________________________________________ > Alsa-devel mailing list > [EMAIL PROTECTED] > https://lists.sourceforge.net/lists/listinfo/alsa-devel > _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
