Self-Reconfigurable Evolvable Hardware System for Adaptive Image Processing

A scalable evolvable hardware processing array

“…With this image the median filter obtains a SAE fitness of 89345, which is higher than the fitness obtained with our system (for any size with the exception of a 1x1 filter). This comparison was made in [12], and since the subject of the paper is the scalability of the system, the results are no longer compared with the median filter output, but they are compared with the results with different sizes.…”

“…The offspring are generated by mutating the parent, which is the best candidate of the previous generation (the circuit with lower fitness). More details can be found in [12].…”

Hexarray: A Novel Self-Reconfigurable Hardware System

“…One of the common uses of EHW is circuit synthesis: analog circuit design [ 40,41,42,43,44] and digital circuit design [45,46,47,48,49,50,51]. EHW is also used in image processing applications, such as developing adaptive filters [30,52] and pattern recognition [53,54,21,55]. In other cases, EHW is used to evolve systems with fault tolerance capabilities, such as fault-tolerant circuits [56,57,58], circuits with fault tolerance using natural redundancy [59], fault-tolerant image processors [60], and high-reliability space applications [61].…”

“…Sekanina's research team at Brno University of Technology, Czech Republic, have conducted considerable research in using systolic arrays in image processing applications [84,90,169,171,172,30]. The utilized system was a 2D array of medium-grained processing elements that were reconfigured using a DPR scheme, as shown in figure 4.4.…”

“…Slow reconfiguration due to the use of DPR solely. In [30] [172] the team compared DPR against the "traditional" VRC, which resulted in the argument that using DPR alone was the best choice.…”
