In this paper I present a robotic device that offers new ways of interaction for producing rhythmic patterns. The apparatus is placed on an overhead projector and a visual presentation of these rhythmic patterns is delivered as a shadow play. The rhythmic patterns can be manipulated by modifying the environment of the robot, through direct physical interaction with the robot, by rewiring the in...

In many digital signal processors (DSPs), variables stored in memory are accessed using address registers and indirect addressing modes. The addressing code used to access these variables can have a significant impact on code size and performance. Thus, one optimization problem DSP compilers face is the problem of minimizing address-computation overhead. This thesis identifies three problems th...
