In addition to many single chip imager and processor, there are several analog chips designed for image processing. In these chips it is assumed that the image has already been acquired using an imager. These chips cannot be regarded as vision chips, but as they present examples of dedicated analog VLSI hardware for implementing vision algorithms, they have been included in this report. There are many analog and digital chips designed for realizing neural network architectures. Some of these chips have been applied to vision algorithms as well. Here, however, we only consider those implementations that have originally been designed for performing a vision task.
