ODALRISC: A small, low power, and configurable 32-bit RISC processor

Configurable processor has become popular recently, since it can be easily configured and extended to increase the performance without losing the flexibility of the programmable processor. In the era of MP-SoC, the base versions of configurable processors need to be small and low power consuming because many processors are extended and placed on a single chip and so each processor should be as efficient as possible containing only the functional units and instructions necessary for carrying out the specific task assigned to the processor. In this paper, we present the ODALRISC processor, which is an ultra small and low power consuming configurable 32-bit RISC processor. The base version is synthesized using 0.18 mum technology, taking less than 16 k gates and consuming power less than 0.1 mW/MHz.
