#125551 - Nmos versus Bipolar(TTL) technology |
Hi everyone,
I'm having great difficulty trying to figure out why CPU's, microcontrollers etc, seem to be fabricated in slow NMOS technology, when the impedement to CPU processor speed appears to be it's frequency or machine cycle throughput. That said, my ALE line on my AT89C51ED2 seems to be ringing quite badly, when running 1mip or 5 mips, Bipolar technology appears to be so much quicker and faster than NMOS/CMOS, but cpu manufactures still insist on using NMOS/CMOS, I wonder what the problem is? Incidently, theres no difference between 40GHz to that of 40Hz, regarding real power consumption, the well known r.m.s. equation tells us that, the only physical difference between 40GHz and 40Hz is the former radiates like hell whilst the latter doesnt, assuming of course both are of equal amplitude. Since there are such fine engineers here, I'm sure we will get to the bottom of things quite quickly..... Darren |
