    We present a parallel architecture for fuzzy controllers and a methodology for their realization as analog CMOS chips for low- and medium-precision applications. These chips can be made to learn through the adaptation of electrically controllable parameters guided by a dedicated hardware-compatible learning algorithm. Our designs emphasize simplicity at the circuit level-a prerequisite for increas... View full abstract»

    The Patent and Trademark Office (PTO) has been fighting patents on algorithms and other computer software for the last 30 years, but it has now decided to throw in the towel. According to draft software patent guidelines just released for public comment, the PTO is now willing to grant a patent on a computer program procedure as long as the patent is limited to a procedure if encoded into a machin...

    Our reconfigurable fuzzy processor (RFP) implements both aggregative and referential operations. Its architecture combines structural and parametric flexibility in a network implementing RFPs as a collection of fuzzy neurons. A fuzzy neural network using a bidirectionally linked series of shared buses facilitates a modular and scalable design environment for the RFP. An appropriate interface, sepa... View full abstract»

    The simulation and optimization of fuzzy systems with neural networks or genetic algorithms on general-purpose processors require fast implementations of fuzzy rule-based systems. We present several adapted implementation concepts that precisely analyze the fuzzy algorithm and are based on lookup tables, optimized rule processing, and digital pulse-duration modulation. These concepts allow general... View full abstract»

    Fuzzy systems based on dedicated digital hardware can deliver much higher performance than those based on general-purpose computing machines. The simplicity and versatility of some successful fuzzy inference algorithms, the advent of high-density, user-programmable logic devices, together with powerful EDA tools, make dedicated digital fuzzy hardware a feasible solution for implementing high-perfo...

    Our analog fuzzy processor features an inference speed of more than 1 million fuzzy logical inferences per second, excluding defuzzification. A rule chip processes fuzzy inferences while a second chip handles defuzzification, a functional division that facilitates flexible system configuration. The chips are compact fuzzy systems that save chip area and are suitable for built-in applications. They... View full abstract»

    We have developed a spatial light modulator technology based on foundry silicon fabrication processes. This technology employs a thin, ferroelectric liquid crystal light-modulating layer at the substrate's surface, producing electrically addressed display devices with resolutions up to 256×256 and frame rates up to 10 kHz. We have also fabricated optically addressed smart-pixel arrays for lo... View full abstract»

    For several decades, designers have used queues to resolve two processor-memory interface problems - long latency and low bandwidth. Here, we discuss the evolution of instruction and branch target queues. We also explore their use to support variable-length instructions and reduce misalignment problems. From the 1956 IBM 7030 (Stretch) to today's PowerPC, we present queue configurations and prefet... View full abstract»
