The concept of a programmable multipurpose computation module for residue arithmetic is introduced. A possible design for the module is also presented. The application of the computation module in mathematical computation, coding, decoding, and scaling is demonstrated. Very high throughput rate is achieved by the use of parallel computation structures and(More)
We identify shape defects on ~300 μm high solder balls by measuring the 3D profile over +/-20 degrees down the ball surface. A broadband line scan interferometer enables measurement of ball height with 125 nm axial resolution.
