A complete hardware implementation of an evolvable combinational unit for FPGAs is presented. The proposed combinational unit consisting of a virtual reconfigurable circuit and evolutionary algorithm was described in VHDL independently of a target platform, i.e. as a soft IP core, and realized in the COMBO6 card. In many cases the unit is able to evolve (i.e. to design) the required function au...

Advances in semiconductor technology are contributing to the increasing complexity in the design of embedded systems. Architectures with novel techniques such as evolvable nature and autonomous behavior have engrossed lot of attention. This paper demonstrates conceptually evolvable embedded systems can be characterized basing on acausal nature. It is noted that in acausal systems, future input ...

In this paper, to conquer the scalability issue of evolvable hardware (EHW), we introduce a novel system-decomposition-strategy which realizes training set partition in the intrinsic evolution of a non-truth table based 32 characters classification system. The new method is expected to improve the convergence speed of the proposed evolvable system by compressing fitness value evaluation period ...

In recent years, nonlinear image processing is increasing in applications, and are better than linear filters in removing noise without disturbing image features. Nonlinear Evolvable Hardware filters are introduced to describe the behavior of filters in the presence of fluctuating signals, edge detection and impulsive noise. The edge detection analysis is especially informative as the degree to...

Evolvable hardware (EHW) is a new technology, which was discovered at intersection of artificial intelligence and the circuit design. Unique hardware architecture is searched for each task. The circuit connection is subject of evolution and the function of such circuit can adapt to dynamic changing environment. Genetic algorithm is used to simulate evolution – its chromosomes encode potential s...

Bandwidth demands of communication networks are rising permanently. Thus, the requirements to modern routers regarding packet classification are rising accordingly. Conventional algorithms for packet classification use either a huge amount of memory or have high computational demands to perform the task. Using a hash function in order to classify packets is promising regarding both memory and c...

In order to retain some degree of decisionmaking ability in a complex and dynamic environment, there are many attempts to build autonomous mobile robots. However, conventional methods pay little attention to the unreliability of sensors. Because of the corruption by noise and the difference of sensitivity, even the same kind of sensors shows different observation under the same condition. This ...

An autonomous self-recovery approach for SRAM-based Field Programmable Gate Arrays (FPGAs) is developed using Consensus-Based Evaluation (CBE). Under the proposed CBE technique, a diverse population of functionally identical (same input-output behavior), yet physically distinct (alternative design or place-and-route realization) FPGA configurations is generated at design time. At run-time, thes...

Images acquired through modern cameras may be contaminated by a variety of noise sources (e.g. photon or on chip electronic noise) and also by distortions such as shading or improper illumination. Therefore a preprocessing unit has to be incorporated before recognition to improve image quality. Generalpurpose image filters lacks the flexibility and adaptability for un-modeled noise types. The E...

Biomimicry at the hardware level is expected to overcome least some of challenges, including high power consumption, large footprint, two-dimensionality, and limited functionality, which arise as field artificial intelligence matures. One main attributes that allow biological systems thrive successful interpretation response environmental signals. Taking inspiration from these systems, first de...
