The first ever image processing chips to handle video images in real time have been introduced by LSI Logic Corp, Milpitas, California. The company claims that the family of four chips offers four times the power of any current digital signal processors, and perform virtually instantaneously all the complex calculations needed to filter out noise, detect edges, extract features and match patterns for image processing applications. The family comprises the L64210 and L64211 variable length shift registers, the L64220 rank value filter, the L64230 binary filter and template matcher, and the L64240 multi-bit filter, the basic four-chip set forming an image processing subsystem that executes the equivalent of 60,000m binary operations plus 1,000m 8-by-8 bit multiplications per second. They are fabricated in LSI’s 1.5 micron HCMOS and are clocked at 20MHz. Aimed at robotic vision systems, image processing and enhancement, radar processing and image and character recognition, they are offered both as standard parts and application-specific building blocks in both commercial and military versions. No price or delivery data was given.
