Small size results in constraints on critical resources such as power, space (for sensors and actuators), and computing cycles, but these robots still must perform many of the challenging tasks of their larger brethren. The need for advanced capabilities such as machine vision, applicationspecific sensing, path planning, self localization, etc. is not reduced by small-scale applications, but needs may vary with the task. As a result, when resources are constrained, it is prudent to configure the robot for the task at hand; both hardware and software. We are developing a reconfigurable computing subsystem for resource-constrained robots that allows rapid deployment of statically configured hardware and software for a specific task. The use of a Field Programmable Gate Array (FPGA) provides flexibility in hardware for both sensor interfacing and hardware-accelerated computation. In this paper, we describe a static reconfiguration architecture we call the Morphing Bus that allows the rapid assembly of sensors and dedicated computation through reusable hardware and software modules. It is a novel sensor bus in the fact that no bus interface circuitry is required on the sensor side -the bus "morphs" to accommodate the signals of the sensor.

Hybrid matter-optical systems offer a robust, scalable path to this goal. Such systems have an ancilla which acts as a bus connecting the qubits. We show that by generating the cluster in smaller sections of interlocking bricks, reusing one ancilla per brick, the cluster can be produced with maximal efficiency, requiring fewer than half the operations compared with no bus reuse. By reducing the time required to prepare sections of the cluster, bus reuse more than doubles the size of the computational workspace that can be used before decoherence effects dominate. A row of buses in parallel provides fully scalable cluster-state generation requiring only 20 controlled-phase gates per bus use.
