Combinatorial floating point processor as an integral part of the computer
This paper describes the Nord-500 which is a dual computer system consisting of a Nord-500 CPU, a Nord-100 CPU and a multiport memory. The Nord-500 CPU executes large time-consuming user programs. The Nord-100 minicomputer acts as a system supervisor for the Nord-500. The Nord-100 runs the multi-mode, multi-user Sintran III/VS operating system and performs all input/output handling, job scheduling and resource allocations. The Nord-100 leaves the Nord-500 CPU free to run user programs with a minimum of system overhead. Up to 64 users can access the system in real-time, time-sharing and batch mode, and share up to 32 mbytes of fast MOS memory and 2300 mbytes of disk storage, and a variety of other peripherals. The basic time of 200 ns executes the majority of the Nord-500's machine instructions. Several Nord-500 processors, with hardware array logic for 32/64 bit floating point multiply/divide, can act as a multiprocessor system supervised by a Nord-100.
