Responding to: ???'s previous message
Waligora Stanislaw said:
I checked the other vendors of the 8051 like architectures and everyone published the Drystone v2.1 C benchmark with their CPU.

Any links?

That everyone publishes Dhrystone results says still nothing on relevancy of Dhrystone for small embedded.
Did you care to read my comments at the link I posted above?

Waligora Stanislaw said:
Result are objective, since run with the same CPU and compiler, so binary code is identical

Which compiler? Which version of the compiler? Can I have that "identical binary"?

max clk freq            01/01/70 00:00      
   Which            01/01/70 00:00      
   300MHz            01/01/70 00:00      
      .            01/01/70 00:00      
         Does that make it effectively 600MHz, then...?            01/01/70 00:00      
            That are the links I found...            01/01/70 00:00      
               Interesting item, but did you notice ... ?            01/01/70 00:00      
                  300Mips, equivalent to 3.6GHz!            01/01/70 00:00      
                     That's slightly misleading ...            01/01/70 00:00      
                        You sure about your math?            01/01/70 00:00      
                           It's confusing ... typical marketing drivel            01/01/70 00:00      
                              Based on the claims you posted            01/01/70 00:00      
                                 Those aren't my claims!            01/01/70 00:00      
                                    Read comments _before_ (not) answering them            01/01/70 00:00      
                                       Architecture speed            01/01/70 00:00      
                                          That was my take too            01/01/70 00:00      
                                             Of course, it does not depend on CLK frequency!            01/01/70 00:00      
                              I cannot see a confusion            01/01/70 00:00      
                                 Not all one-clocker mfg's make the same claims            01/01/70 00:00      
                                    But...            01/01/70 00:00      
                                 comparison of 12- and less-clockers            01/01/70 00:00      
                                    Very nice!            01/01/70 00:00      
                                    Cool!            01/01/70 00:00      
                                    Good overview            01/01/70 00:00      
               Another link            01/01/70 00:00      
                  Dhrystone?            01/01/70 00:00      
                     Yes ... one could argue that the core is hobbled            01/01/70 00:00      
                        to sell IS useful... ;-)            01/01/70 00:00      
                     Dhrystone            01/01/70 00:00      
                        give data            01/01/70 00:00      
                  I find it useful...            01/01/70 00:00      
                     Nonsense            01/01/70 00:00      
                        Nice attitude...            01/01/70 00:00      
                        One thing that would be useful for FPGA            01/01/70 00:00

                              Here it is ... It's simple arithmetic            01/01/70 00:00      
                                 Not at all!            01/01/70 00:00      
                                 You missed the "at the same frequency" part            01/01/70 00:00      
                                    You're right, in a sense ...            01/01/70 00:00      
                                       Still thinking of the DT8051 as 12-clocker            01/01/70 00:00      
                                          Gee ... I can see where I went off the track!            01/01/70 00:00      
                                             You deserve respect for that...            01/01/70 00:00      
                                             Very easy to miss things            01/01/70 00:00      
                                                It is a shame the documentation is so superficial            01/01/70 00:00
