The complexity of today's applications increases with various requirements such as execution time, code size or power consumption. To satisfy these requirements for performance, efficient instruction set design is one of the important issues because an instruction customized for specific applications can make better performance than multiple instructions in aspect of fast execution time, decrease of code size, and low power consumption. Limited encoding space, however, does not allow adding… CONTINUE READING

Key Quantitative Results

  • In our experiment, the architecture augmented with DIAMs shows about 10% code size reduction and speed up on average, as compared to the base architecture without DIAMs.
  • The experiment has revealed that the processor augmented with DIAMs requires a small amount of additional hardware cost, but also that it reduces code size by 8.4%, and increases code speed by 9% on average, in comparison with the original processor without the DIAM.
