A Microprocessor-Based Interpolator

마이크로프로세서를 이\ulcorner나 인터폴레이

In this paper we present a microprocessor-based interpolator using algebraic arithmetic method. The interpolator consists of 2900 "bit-slice" microprocessor chips and 0.5K ROMs of 36-bit microprogram memory. The system design is an instuction-data-based architecture with 250ns cycle time. A significant feature of the interpolator is that it has flexibility, very fast interpolation speed of 250 K pulses/sec, and performs additional functions simultaneously. Throughout the paper detailed explanations are given as to how one can design the hardware and software, and experimental results are presented.presented.
