  • Serial bus for master/slave computer system
    Patent number: 4688171
    Abstract: A serial to parallel bus converter (11) enables a slave computer (13), having a parallel bus input (19) to be controlled by a master computer (15) via a serial bus connection (14). The converter (11) interprets commands from the master computer (15) to provide appropriate control commands for the slave computer (13). Instructions received from the master computer (15) are provided to the slave computer (13) when complete commands from the master computer (15) are received by the converter (11). The converter (11) uses an intermediate bus (29), which is connected to the RAMs (27), ports (41-44) and a control register (45) for communicating with the slave computer (13), a UART port (31) for communicating with the master computer (15), a microprocessor (25) and a programmable read only memory (PROM) (33) for the microprocessor (25).
