Serial System Bus + Protocol

I led a group of three to design and implement the protocol and architecture of a serial system bus with the following features.

• Up to 12 masters and 6 slaves
• Priority-based arbitration
• Split transactions
• Interfaces to external buses with automatic baud rate detection and handshaking
• Custom protocols for internal and external buses

We implemented it on an Altera DE2-115 and demonstrated by sending a packet of data through three similar boards connected chained through the external bus interfaces.
