Terminal management bus

A bus (10) uses DS encoding with an additional wire framing the signal on the Data and Strobe lines, allocating control of the lines by a master (12) or a selected slave (14). A data clock can be recovered from the Data and Strobe lines, eliminating clock skew between circuits. Slaves (14) with diff...

Zusammenfassung:A bus (10) uses DS encoding with an additional wire framing the signal on the Data and Strobe lines, allocating control of the lines by a master (12) or a selected slave (14). A data clock can be recovered from the Data and Strobe lines, eliminating clock skew between circuits. Slaves (14) with differing speed abilities are supported by generating an address portion of the message at a first speed and the remaining transaction portion at the full capabilities of the selected slave. Further, the slaves (14) can adapt their bus drivers to various voltage levels to accommodate master circuits using different processing technologies. The bus (10) is scalable to allow high bandwidths.
