A new vision system: programmable logic devices and digital signal processor architecture (PLD+DSP)

The authors show a way to establish a good structure for an image processing system. Image processing algorithms are classified as a function of the input/output information structure. Then a whole system is created, with different processing architectures inside, one for each group in the classification. The main devices in the whole machine are a digital signal processor (DSP), and specific hardware designs into erasable programmable logic devices (EPLDs). It is shown how these specific designs can be made with a few different printed circuit boards, and specific circuits are loaded from a library into EPLD chips. This library is prepared in the computer, and the machine is easily adapted to a specific application
