ABSTRACT:
The present invention creates dedicated point-to-point or point-to-multipoint links between different devices along plural busses. Synchronized clocks to each device enable proper timing of read and write operations to/from the bus. The bus connection between the devices are selectively switchable so that dedicated bus connections between devices can be switched on and off as needed. Since the links are point-to-point between sending and receiving devices, the throughput of star-like topology (e.g., Ethernet) can be achieved with very low latency. An arbiter creates the link. The link is established indefinitely, for as long as the arbiter configures it to exist. Additional transactions through the link require only a frame signal to be asserted by the sender and the frame signal to be interpreted as a“data ready” signal by the target.
