1. A computer comprising:

  • a hardware accelerator that performs mathematical operations; and

    a driver level comprising;

    a first lookup table, wherein the first lookup table includes first data for calculating a mathematical function using a first level of accuracy; and

    a second lookup table, wherein the second lookup table includes second data for calculating the mathematical function using a second level of accuracy, wherein the first level of accuracy achieves a more accurate solution than the second level of accuracy; and

    a driver that executes the data from the first lookup table and the second lookup table, and wherein the driver sends instructions to the hardware accelerator, wherein executing data in the first lookup table for solving the mathematical function using a first level of accuracy uses more energy than executing data in the second lookup table for solving the mathematical function using a second level of accuracy.
