silabs goes as high as 100MHz at 1 clock = 100 times faster than "the standard" Slightly less as the instruction cycle per instruction is different for the 1- (and 4-) clockers. However, the SiLabs perform remarkably well, according to my findings it's the best what you can get among the 1-clockers. My "benchmark" indicates something around 90-times improvement over the 12MHz/12clocker "vanilla", that's around 23 times faster than the 'S8253 would be at 22.118400MHz. These figures are slightly overoptimistic as they assume branch cache hit each time, so the real number would be maybe around 80 times for the vanilla. And of course it depends on the particular instruction mix and maybe other circumstances (e.g. external external memory access), we all know the value of benchmarks... JW |
