Both? I spent some time searching in Acrobat Reader, just to get a "feel" for this feature (I didn't get one!), but haven't yet sat down and read the doc's yet. I'm still trying to assess whether this part can do the job "better" or more easily than the somewhat slower Maxim/Dallas part.


For tight timing of a short loop, you might also want to consider a completely different architecture: have you had a look at the AVRs? Their execution rate is pretty uniform and easy to predict. Also - 8052.com forgive me - PICs are known for similar value, with increased power in the new PIC24s and dsPICs (but this is only what I've heard, I really don't like the PICs... :-)
The proof is there: on the net, there are several direct video generation projects on AVRs and PICs (I'd even guess based on the pictures they published that the commercial microVGA of Dontronics is dsPIC based); yet there is only one, even that (Phillip Gallo will please kindly forgive me) unfinished, with the '51s around....

   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
