Automatic Instruction Set Extension and Utilization for Embedded Processors
There is a growing demand for application-specific embedded processors in system-on-a-chip designs. Current tools and design methodologies often require designers to manually specialize the processor based on an application. Moreover, the use of the new complex instructions added to the processor is often left to designers’ ingenuity. In this paper, we present a solution that automatically groups dataflow operations in the application software as potential new complex instructions. The set of possible instructions is then automatically used for code generation combined with high-level arithmetic optimizations using symbolic algebra. Symbolic arithmetic manipulations provide a novel and effective method for instruction selection that is necessary due to the complexity of the automatically identified instructions. We have used our methodology to automatically add new instructions to Tensilica processors for a set of examples. Our results show that our tools improve designers productiv...
