A high-speed fuzzy co-processor implemented in analogue/digital technique

A context switchable fuzzy inference chip

“…Analog fuzzy chips yield high inference speed with relatively simple and compact architecture, as well as good compatibility with sensors [24], [28]. However, analog implementation lacks extensibility and flexibility compared to digital implementation [29]. Digital fuzzy chips have good programmability and flexibility by employing logic and memory circuits, as well as good compatibility with other digital systems [24], [29].…”

“…However, analog implementation lacks extensibility and flexibility compared to digital implementation [29]. Digital fuzzy chips have good programmability and flexibility by employing logic and memory circuits, as well as good compatibility with other digital systems [24], [29]. Nowadays, with powerful formal design methodology and good design tools support, the realization of digital systems is generally more efficient.…”

Design and implementation of a reconfigurable fuzzy inference processor

“…is more appropriate to cater for the design constraints [77,80]. Fuzzy inference processor is a good candidate, since it is able to offer high execution speed for time-critical applications [81][82][83].…”

“…There is no need for analog-digitalconversion (ADC) and digital-analog-conversion (DAC) circuits [113,122]. However, analogue circuits implementations lack extensibility and flexibility compared to digital implementations [82,111]. Analog implementations also suffer from relatively low accuracy [84,102], since they are susceptible to noise disturbances and process variations [124].…”
