Abstract:
Designing a general structure for fast image processing algorithms to compute the
image intensity for low level 3x3 algorithms having the same parallel calculation
method but with different kernel is our goal in this paper. Using DSP slice module
inside the FPGA was an objective task to get the advantage of it as a faster, accurate,
higher number of bits in calculations and different calculated equation maneuver
capabilities. Using the remade design scheme can solve many problems such as
redesign time consumption, increasing the calculation accuracy by using high number
of bits in calculations more than the regular logic gates, saving FPGA resources is
one of the advantages we got by using the general structure design especially if we
need to make more than 3x3 low level algorithm for the same project we can select
which algorithm to be calculated at certain time for the same structure as we take an
example in this paper by selecting between Gaussian filter and Sobelx edge detector
as an example. The General structure is capable to be modified to add other
algorithms which have the same calculation methods. Other designers as mentioned
later an example on this paper uses separate fixed design for each algorithm with
maximum 12bit calculation accuracy.
