Though the Apple iPad and the Samsung Wave most assuredly share  the same brain, 
EE Times would like you to know there's  more to a chip than its core -- analyzing Apple's system-on-a-chip  designs in detail back to early iPhones, the publication noticed that  Cupertino's silicon 
both has custom design quirks on  top of ARM 
and shows heavy influence from Samsung as well.  
EE Times claims that while the A4 and Samsung S5PC110 are  similar, there are certainly differences, enough to call the A4 a custom  design. Essentially, Apple has a taken a one-size-fits-all product  originally engineered to meet the needs of a broad range of OEMs and  reduced its complexity, footprint, and cost to match Apple's particular  goals. As far as whether PA  Semi or Intrinsity  had a hand in that design, the authors suggest only the latter seems  very involved. What all this means for intellectual property questions  is anyone's guess -- we'll let the lawyers fight that one out -- but  when you encounter diehard fans that claim one's ripping off the other,  at least now you'll be able to calmly explain the situation.
