An arithmetic processor chip for use in robotics has been designed in 4 μm CMOS technology. The chip functions as a slave processor to a general purpose microprocessor host and is able to perform robot arm coordinate transformation calculations for use in real-time control applications. A parallel-processing, multipipelined architecture is used to produce a 45 mm2 chip for which a machine cycle time of 200 ns appears possible. The general nature of the architecture of this microprogrammable processor renders it useful for a range of computational tasks in robotics
