 		 #127309 - Advertising.
Responding to: ???'s previous message
If they pipeline the architecture such that if you branch out of a loop and into another it takes an indeterminate period of time to reload the pipeline,

It should never take an "indeterminate" amount of time. There should only be two cases to consider - cache hits and cache misses. The former is fast, the latter slow due to penalties for reloading/etc.

How'd they manage to sell that? This clearly makes their claim of "100 MIPS" false, except for loops shorter than whatever the pipeline is.

Why ... isn't that what all advertising is based on ? Giving maximum number only reached in ideal cases ? There's no "except" in advertising - if they can somehow make the thing deliver 100 MIPS, their claim is true. Only if they could not, under any circumstances, reach 100 MIPS, they would be lying.

   You cannot say without more information            01/01/70 00:00      
      You've got it! That's the problem, for sure.            01/01/70 00:00      
         Synchronization            01/01/70 00:00      
            True enough, but in this case            01/01/70 00:00      
   So you can be happily chugging away            01/01/70 00:00      
      That renders the SiLabs architecture unuseable            01/01/70 00:00      
         Can't You Trurn it off?            01/01/70 00:00      
         Advertising.            01/01/70 00:00      
            a better term would have been "unspecified"            01/01/70 00:00      
         if what you want is to bitch, the cache stinks, if            01/01/70 00:00      
            No ... it's not just a complaint ...            01/01/70 00:00      
               experience and the other is stated already            01/01/70 00:00      
                  it's not quite that simple ...            01/01/70 00:00      
                     does not matter, in this case an advantage            01/01/70 00:00      
                        Yes, same length, irrespective of path            01/01/70 00:00      
   can you explain more?            01/01/70 00:00      
      It uses a pipeline to achieve the high speed            01/01/70 00:00      
         why pipeline??            01/01/70 00:00      
   branch cache            01/01/70 00:00      
      i dont know about slightly unpredictable            01/01/70 00:00      
      I second this.            01/01/70 00:00      
      It's called "branche cache" rather than pipeline?            01/01/70 00:00      
         They're two different things.            01/01/70 00:00      
            This flush and refill process is what I feared            01/01/70 00:00      
         you might also try something completely different            01/01/70 00:00      
            well ... maybe ...            01/01/70 00:00      
   what is the problem?            01/01/70 00:00      
      The problem is blaming the pipeline ...            01/01/70 00:00      
         oh, I wish            01/01/70 00:00      
         Exactly ...            01/01/70 00:00      
      That reference is helpful            01/01/70 00:00      
         not a "litterary masterpiece" but after reading            01/01/70 00:00
