A MICROPROCESSOR-BASED INTERPOLATOR

A MICROPROCESSOR-BASED INTERPOLATOR

In this paper we present a microprocessor-based interpolator using algebraic arithmetic method. The interpolator consists of 2910 "bit-slice" microprocessor chips and 0.5K ROMs of microprogram memory. The system design is an instruction-data-based architecture with 250ns cycle time. A significant feature of the interpolator is that it has flexibility, very fast interpolatioon speed of (max) 250K pulses/sec, and performs additional functions simultaneously. Throughout the paper detailed explanations are given as to how one can design the hardware and software of the interpolator efficently. In addi- tion to hardware and software design, experimental results are pressented.ressented.
