CALCULATION OF DECIMAL LOGORATHIM
Ramin Tajallipour
2
Why logarithm? - Simplify the difficult multiplication
In most computer systems the multiply operations are done sequentially. But in certain applications, such as digital filtering, its often desirable to implement a number of multiply operations simultaneously to increase the data rate - Simplify the difficult multiplication

I want to compute the decimal Log
Why Decimal Log? Just precision For instance, In financial application the precision play great role because might be a billion dollar Why we don’t take advantage of log- base 2 ? Because it’s not error free, and we should once convert the decimal number to binary and at final we should convert it back. How we can do this? - Linear segmentation of logarithm curve - Curve fitting - Hybrid approach using ROMS and algorithm for iterative method. - Iterative method

Materials and Methods for
- Simplifying the number to numerical base L= which R is based 10 - By Iteration and simple multiplication - Simulate the algorithm via MATLAB - Implement by Verilog HDL
