Hardware Approximation of Single Precision Elementary Function with Second Order Interpolation
Shen Xu-bang · Microelectronics & Computer · 2002
The sim plest function implementation is look-up table.Combined with simple arithmetic operation,look-up table can also be applied in single precession function app roximation.Had introduced other same research,a modified look-up table archit ecture based on second order interpolation was proposed in this paper.The modif ication reduces the constant ROM area,decreases the total delay,and requires l ow precession arithmetic operation.The unified architecture can implement all t he single precision approximation of elementary function.
