1701-inputs.png     Several designers have recently asked about how to estimate instruction usage by various algorithms on the ADAU1701, since its compiler does not itemize instruction usage by individual blocks.  The attached spreadsheet lists most of the ADAU1701's toolbox blocks with the instruction count for most of their possible conditions (grown inputs and outputs, etc.).  It's easier to build a more efficient project when one knows how much each of the blocks cost.  For example, as shown at left:  It pays to un-check any unused channels on the Input block since they use instructions.
