Hi all! I am currently designing a prototype board using the blackfin 537. This chip has an array of ground pins in the center, which is only accessible to my ground layer via two small gaps. I would like to avoid placing vias between the BGA grid. Question: must all of these balls be contacted, or may I leave 2 or 4 uncontacted and place a via instead to connect the other ones to th...

I am starting to learn the DSP by using the Analog DSP. I am wondering which one is "best" - I do not have target application now. just for learning DSP. What I mean "best" is that the chip architecture is current, stable, widely used, easy use(?), and the support for the chip last longer - some chip might be outdated. TigerSharc? Sharc? - will be replaced by TigerSharc? Blackfin?

With the low price of flash-mem and maturity of mp3, I'm surprised that 'talking books' are not commonly available - cheaply; where you would just change flash-cards. Syncronising the 'writing with the sound' would also be good for language learning ? Perhaps even minimal cartoon-like graphics for stories for kiddies ? Who knows about the Blackfin CPU from Analog devices ? Thanks ...

Hi all, Does anybody happen to know if the 400 and 500 MHz types of the ADI BF533 chips share the same silicon (and are just selected)? In other words: Do I have to expect any changes in EMI when using the 500MHz part instead of the 400MHz part, both running at the same speed (approx. 250MHz)? Thanks, Andre

I've recently been trying to get the SDRAM working on my BF533 EZ-Kit Lite, to no avail! The development environment is supposed to setup the SDRAM registers by default, if this feature is enabled, which it is. I've also tried setting them up manually. The problem is if I try and modify the memory, say address 0x00000000 or 0x00000002, using the memory viewer it doesn't actually succeed ...
