Managing Dynamic Precision on Reconfigurable Hardware (Summary)

چکیده
In typical VLSI and processor based architectures, the computational units have fixed precision which can not be modified during computation. The precision of operands implemented in such architectures is based on the worst case bounds for the precision of the input values. Some applications also need precision much higher than that available in typical hardware architectures [3]. For such long-precision arithmetic, software algorithms are employed to obtain the desired precision. Long-precision computations typically operate digit by digit, serially. The iterative computations mean that the execution time of an operation increases as the required precision increases. Performing computations using the exact precision required for accurate results can reduce the resources utilized.
