Claims
- 1. An adapter for connecting at least three devices to a high performance parallel interface channel connected in a "Daisy chain", each of said devices being capable of both sending and receiving bursts of data with a data clock, said adapter comprising:
- inbound receiver means connected to said channel for receiving said bursts of data and data clock;
- decoder means for decoding routing information contained in said bursts of data;
- pass through logic means connected to said decoder means for interpreting said routing information;
- first latch means connected to said inbound receiver means for temporarily storing data bursts;
- second latch means connected to said first latch means for accepting data bursts when said routing information identifies a device to which the adapter is connected;
- data selector means connected to said first latch means for selecting data from said device or from said first latch means;
- outbound transmitter means connected to said channel for transmitting bursts of data and a data clock, said outbound transmitter means also being connected to said data selector means for transmitting data bursts from said first latch means when said routing information does not identify said device.
- 2. The adapter recited in claim 1 further comprising clock synchronizing means connected to receive said data clock from said inbound receiver means and passing said data clock directly to said outbound transmitter means when said routing information does not identify said device.
