  • Bus steering structure for low cost pipelined processor system
    Patent number: 4057846
    Abstract: Logic circuitry is provided for controlling the transfer of data between 1) a low cost pipelined processor and its associated memory, 2) between the processor and input/output devices, and 3) between the input/output devices and memory. A plurality of unidirectional busses are provided to interface the processor and memory and a bidirectional buss is provided to interface with the input/output devices. The logic circuitry provides a control function to steer data over the proper buss structures interconnecting the processor, the memory and the input/output devices and provides those interconnections in a manner which allows the processor to overlap input and output functions.
