Rating it with virtual GHz is good for "marketing" but it says nothing usable in real applications (at least for engineers).

A virtual clock rate of 3.6GHz means that an "ADD A,Rn" instruction is performed 3.6GHz/33MHz = 109 times faster than a 12-clocker doing it at 33MHz clock speed.

The virtual clock rate can be enormeously helpful when comparing all these many 12-, 6-, 4-, 2- and 1-clockers arround.

It is really nonsense. It looks like you never did any real application with that IP Core.

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      
                           Still waiting            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

                                                   Any alternative?            01/01/70 00:00
