ABSTRACT:
A well-logging well-site data acquisition and data processing system is disclosed. A central processing unit including a main memory and a single data bus is provided for data transfers with a first plurality of peripheral units. A plurality of serial link units are also provided. Each serial link unit includes a plurality of serial data input/output channels where each serial channel sends on transmit lines and receives on receive lines serial data between a second plurality of peripheral units connected to a serial link unit. A processor interface unit is provided for controlling the transfer of data between the host central processor unit and the plurality of serial link units. A microprocessor unit is provided as a communications controller for initiating the transfer of data between the plurality of serial link units and the processor interface unit. The plurality of serial link units in cooperation with the microprocessor unit and the processor interface unit enable the simultaneous input/output transfer of data to the peripherals to occur thereby increasing the effective data transfer rate of the system.
