So how do all these features work together? What are some real measurements that can be examined to objectively determine the performance of the RX? Dhrystone is a benchmark that has been around for years. And while it is not the best measure of all the things that make an embedded system perform, it is a good baseline. The RX clocks in at a very impressive 1.65 Dhrystone MIPS/MHz. Because of the zero-wait state, 10 nS flash, this performance scales linearly right up to 100MHz delivering an impressive 165 DMIPS.
