Resumo(s)
This paper describes part of project that
implemented the image processing of a CMOS sensor for
endoscopic purposes. The sensor is a small sized device of
1x1mm2 and the image processing has been done inside a FPGA.
This part of the work describes the implementation of the
Gamma function with a balance between the resources needed
and the accuracy. A linear piecewise solution was used that stores
the values for 31 gamma functions with values ranging from 1 to
4 with 0.1 steps. The solution developed is 10 bit based, was coded
in VHDL and is implemented in a Spartan 6 FPGA. The results
show that it is an accurate solution that has a small footprint in
terms of used resources.
