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).
Advantages include a capability of directly programming the slave computer (13) from the master computer (15), and the ability to verify transmission between the master computer (15) and the slave computer (13). The system has an ability to use serial transmissions between the computers (13,15), even though the slave computer (13) may not have serial data transmission capabilities, by using the converter (11) as a buffer.
