摘要： A computer architecture for avoiding a deadlock condition in an interconnection network comprises a messaging buffer having a size pre-calculated to temporarily store outgoing messages from a node. Messages are classified according to their service requirements and messaging protocols, and reserved quotas in the messaging buffer are allocated for different types of messages. The allocations of the reserved quotas are controlled by a mechanism that, to prevent overflow, limits the maximum number of messages that can be outstanding at any time. The messaging buffer is sized large enough to guarantee that a node is always able to service incoming messages, thereby avoiding deadlock and facilitating forward progress in communications. The buffer may be bypassed to improve system performance when the buffer is empty or when data in the buffer is corrupted. In addition, a multicast engine facilitates dense packing of the buffer and derives information from a message header to determine whether there is a multicast to perform and to permit passage of messages. Other considerations to reduce the buffer size are incorporated.

摘要： A multiprocessor system includes a plurality of nodes and an interconnect that includes routers. Each node includes a reliable packet mover and a fast frame mover. The reliable packet mover provides packets to the fast frame mover which adds routing information to the packet to form a frame. The route to each node is predetermined. The frame is provided to the routers which delete the route from the routing information. If the frame is lost while being routed, the router discards the frame. If the packet is received at a destination node, the reliable packet mover in that node sends an acknowledgment to the source node if the packet passes an error detection test. The reliable packet mover in the source node resends the packet if it does not receive an acknowledgment in a predetermined time. The fast frame mover randomly selects the route from a plurality of predetermined routes to the destination node according to a probability distribution.

摘要： A system and method for acknowledging receipt of messages within a packet based communication network. A sending node generates a data packet within an upper layer, and transmits the data packet to a receiving node using a lower layer. The lower layer generates and transmits a pseudo reply packet to the upper layer in response to an acknowledgment received from the receiving node. The pseudo reply packet notifies the upper layer of the sending node that the receiving node successfully received the data packet and removes the burden of having an upper layer of the receiving node generate an actual reply packet.

摘要： A system and method dynamically determines the topology of a source node routing network while having a minimal effect on network performance and without requiring expensive hardware to implement. A source node generates a ping frame. The source node transmits the ping frame to a first source router that is coupled to the source node. The first router transparently identifies the frame as a ping frame and creates an echo frame that is transmitted back to the source node. The first router identifies the port from which the ping frame is received and places this information in the header of the echo frame along with an echo frame identifier. The source node receives the echo frame and identifies routers and nodes to which a ping frame has not been sent based upon the connectivity information in the received echo frame. The source node continue generating and transmitting ping frame to all nodes and routers in the network. The source node identifies loops in the topology to avoid repetitive checking and identifies link and router failures. The topology exploration technique is transparent to the routers The topology exploration techique can be implemented during slow traffic periods with no increase in network latency or the technique can be implemented during high traffic periods and result in only a minimal increase in system latency because ping frames are small and are transparently sent to the control frame handler of the destination router or node.
摘要翻译：系统和方法动态地确定源节点路由网络的拓扑，同时对网络性能影响最小，而不需要昂贵的硬件来实现。源节点生成ping帧。源节点将ping帧发送到耦合到源节点的第一源路由器。第一个路由器将该帧透明地识别为一个ping帧，并创建一个发送回源节点的回波帧。第一个路由器识别从其接收ping帧的端口，并将该信息与回波帧标识符一起放置在回波帧的报头中。根据所接收的回波帧中的连通性信息，源节点接收回波帧并识别尚未发送ping帧的路由器和节点。源节点继续生成并发送Ping帧到网络中的所有节点和路由器。源节点标识拓扑中的循环，以避免重复检查，并识别链路和路由器故障。拓扑探索技术对于路由器是透明的。拓扑探索技术可以在较慢的流量周期内实现，而不会增加网络延迟，或者在高流量时段内可以实现该技术，并且只能使系统延迟最小化，因为ping帧并且被透明地发送到目的地路由器或节点的控制帧处理器。

摘要： Methods and apparatuses are described for an Intellectual Property (IP) Generator for estimating timing, area, and power characteristics of an electronic system design. The IP Generator receives a user-supplied file having data describing a configuration of an IP design having multiple levels of hierarchy. The IP Generator also receives user-supplied technology parameters and data-flow information. The IP generator correlates estimated timing, area, and power characteristics for each IP sub component based on the user supplied technology parameters, data-flow information and configuration parameters. The IP generator reports the timing, area, and power estimates to a user via a graphic user interface prior to a transformation of a Register Transfer Level (RTL) design into the gate-level circuit design.
