This poster describes our experiences, materials and plans using the Atmel AVR, a RISC microprocessor, for teaching beginning computer organization at the college level. In particular, we use this microprocessor, typically packaged into the Arduino, to give hands-on experience with: (1) Assembly language programming, including ISA (16 bit instructions), multiple types of branches, multiple addressing modes, (2) C language programming, (3) interrupt programming, (4) I/O programming, and (5) programming on-board components, e.g., timers/counters.

A solution to the correspondence problem using constraint satisfaction is described. It uses a real-time line-fitting algorithm to detect changes in a point's motion parameters as they happen. A trajectory is hypothesized for a single point's motion. Since the event detected may be wrong, multiple trajectories are hypothesized for each point. A correspondence is drawn from the set of hypothesized trajectories. The algorithm is robust, working on noisy and non-rigid motion data, and does not use false precision.>
