Abstract
Abstract A general purpose array processor is made up of a plurality of independent processing units. A digital host computer provides the overall control for the system. An interface unit is connected to receive instructions and data signals from the host computer and then to autonomously and selectively distribute the instructions and data to other units within the system and to transmit status, control and data signals to the digital host computer. A transfer controller unit is connected to a bulk memory and to the interface unit for receiving the instructions from the interface unit and for autonomously and selectively transferring data signals from the bulk memory means to an arithmetic unit which is also connected to the interface means and receives instructions therefrom for subsequently autonomously and selectively performing arithmetic functions on the data transferred by the transfer controller unit. An input controller unit may be provided for receiving data from a data source. The input controller unit is connected to the other units and to the bulk memory and receives the data from the source of data and reformats and transmits the reformatted data to the bulk memory. The arithmetic unit has a fixed point and a floating point adder for flexiblility of operation.
