We need one of these. Who wants to write a PCM article like this for the LS1? <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: We need one of these. RE: "we need one of these"
You have hit on some past good stuff, e.g., the good old days. When data books were available that said it all. An 8bit micros and 16 bit microcontrollers running at 12Mhz were what was happening.... Well add a few hundred thousand(million) transistors to the mask, bookoo more pins, new microcode, faster clocks and lower VCC etc.. and all of a sudden, the arch is not so simple.
Now if your a real embedded software engineer (which I am not) you can weather any of the recent and not so recent changes in the semiconductor evolution. But for most of us, its just too high level. Hell, we call it getting sloppy, e.g, you have the memory capacity, speed, and combined with bandwidth, hell code no longer has to be that efficient.
And then theres "FLASH" and incircuit programming. To get an idea how old I am, Im still burning EPROMS that are only 8K by 8...
