 		 #152802 - that's why they use 'C'

Then, this sounds like a typical example where speed can be traded in for memory (and maybe a bit of additional logic).


i think "this sounds like a typical example" of what I call "PC coding" where the efficiency of the code is ignored for the convenience of the programmer.

Isn't that why folks use HLL's? That sacrifice is a given with HLL's, isn't it?

The ARM types with which I've had intimate contact all had built-in SDRAM channels as well as the usual FLASH/SRAM channel. I was amazed at how little external hardware was needed, as the desired peripherals were typically built-ins. The whole system, IIRC, had 7 IC's, aside from the four voltage regulators.
