ABSTRACT:
A digital crossbar switch designed to facilitate easy and flexible interconnection of up to 8 data ports. The device includes 8 bidirectional ports, each 8 bit wide. Interconnection of the ports is controlled by 32 stored control memory locations associated with each port. The controlling memory locations can be changed dynamically without interfering with data flow. Additional program flexibility can be achieved by providing each port with a 16 word first-in first-out data buffer. The capability to bit reverse the data on any of the ports is also provided to simplify the interconnection of busses from different architectures. The device is fully expandable to wider busses, has extensive test capability and a master reset is provided for system initialization.
