Neat article discussing the leading platform of new class of embedded products. PSoC digital system not just provide high configurability, but also distributed processor power thanks to the integrated ALU-based 8-bit datapath. These datapaths may be chained with datapaths in neighboring UDBs to achieve higher precision functions. The datapath includes a small RAM-based control store, which can dynamically select the operation and configuration to perform in a given cycle. All the on chip analog performance is based on a highly accurate absolute voltage reference with less than 0.2% error over temperature and voltage too.
