Abstract: A computer system having at least a first microprocessor for processing information and a first memory coupled to the first microprocessor via a first point-to-point interface. The first point-to-point interface provides communication of signals between the first microprocessor and the first memory irrespective of the phase of the signals received by either the first microprocessor or the first memory. The first point-to-point interface includes a first point-to-point circuit in the microprocessor for receiving the signals from the first memory. The first point-to-point circuit and the microprocessor comprise a single integrated circuit in some implemented embodiments, providing ease of construction and design of systems having a variety of topologies.

Abstract: A unidirectional point-to-point communication apparatus for communicating messages between two computing resources irrespective of the phase of the messages, length of a communication path between the two computing resources and internal speed of the two computing resources. The communication apparatus has a high speed communication bus coupling a transmitter and a receiver for transmitting the messages from the transmitter to the receiver. A high speed communication clock is coupled to the bus and the receiver for timing the messages transmitted on the high speed communication bus between transmitter and the receiver. A large data buffer is coupled to the high speed communication bus after the receiver for storing messages transmitted between the transmitter and the receiver.
