 		 #115652 - that is not the argument
Responding to: ???'s previous message
With a small, cheap MCU, which is what an 805x is supposed to be, processing bandwidth is one limited resource, and memory usage is another.

That is not the argument, the argument is that a comparison (such as a LCD driver) that does not measure throughput does not tell the full story. If I can get less memory use at same or greater speed - thank you.

When you say "throughput," what, exactly, do you mean? Is it the rate at which the serial port spits out the data? Is it the rate at which it executes FFT's, autocorrellation, etc? Is it the rate at which it perfoms triple DES?
For my app I barely scrape by with a 50 MIPS SILabs chip (I use the 100 MIPS versions and test with the 50MIPS to ensure I have 'headroom'). If I could drop to 25MIPS by changing language (No way, the 'speed code' is already assembler) I'd save substantial amounts of money.
