摘要： The Scalable Coherent Interface (SCI) standard of the Institute of Electrical and Electronics Engineers is intended for fast, high throughput, point-to-point, unidirectional links to high-performance multiprocessor systems. A system is provided for routing packets with a plurality of data bits and target identity code bits through a packet routing switching network. The packets are transmitted from source nodes through the switching network to target nodes that are designated by the target identity code bits. Operational rings are used to link output ports of switches of the output stages to input ports of switches of the input stage wherein each operational ring is identified by ring identity code bits associated with the input stage switches of the operational rings and has at least one node which is capable of performing a function with the data. Recirculation rings are used to link output ports of switches of the output stage to input ports of switches of the input stage. The recirculation rings have no functional nodes in them. Each output port of the output stage switches is coupled to either an operational ring or to a recirculation ring, and the packets are transmitted from source nodes through the operational rings. In the event any of said packets are misrouted, then the packets are transmitted through the recirculation rings or through the operating rings that do not contain the designated target nodes until the packets reach their respective designated target nodes.

摘要： The Scalable Coherent Interface (SCI) standard of the Institute of Electrical and Electronics Engineers is intended for fast, high throughput, unidirectional links to high-performance multiprocessor systems. Key elements of the protocol for SCI include: (a) a "new/stale" bit which is generated in a data packet for detecting stale packets to discard; (b) an idle.cc which is an idle bit to be inserted between packets for detecting lost packets which toggles when the idle bit has circulated around the ringlet; and (c) a scrubber node in each operational ring of an SCI network which toggles "new/stale" bits from a "new" state to a stale state when they are received at the scrubber node. The "new/stale" bit is also set to a "new" stale bit when a packet is generated in a source node in a first operational ring for transmission to a target node in a second operational ring. A scrubber node is located as the first node of each operational ring of the network. The new/stale" bit and the idle circulation (idle.cc) is used to keep track of misrouted and lost packets. Each of a plurality of switches of the switching network is assigned to one of a plurality of rows of the switches and to one of a plurality of stages of the switches. Each of the switches has a plurality of input ports and output ports associated therewith. Input ports are coupled to the switches of the input stage, and output ports equal in number to the number of input ports are coupled to the switches of the output stage. The number of switches in a row is equal in number to the number of stages of the switching network. The packets are transmitted from the input ports to the output ports through operational rings that are connected thereto until each of the packets reaches a designated target node.

摘要： Multi-stage switching networks may be constructed and expanded from small to very large networks that are contained within a compact physical volume. This is accomplished by replication of a pre-selected network module containing switches by a rotating, folding and squaring process that substantially reduces the length of connections between switches. This geometry allows very large networks by inductively combining smaller networks into larger networks. In networks constructed with this geometry, the length of the longest connections between switches is proportional to the square root of the number of ports provided by the network.

摘要： The Scalable Coherent Interface (SCI) standard of the Institute of Electrical and Electronics Engineers is intended for fast, high throughput, point-to-point, unidirectional links. It is to serve high-performance multiprocessor systems. A number of key elements are defined as part of the protocol for SCI. These include: (a) command.old which is a bit in transmitted packets for detecting stale packets to discard; (b) idle.cc which is an idle bit to be inserted between packets for detecting lost packets which toggles when the idle bit has circulated around the ringlet; and (c) idle.ac which is an idle bit which toggles when all operational nodes have had an opportunity to transmit. In addition, SCI contemplates the implementation of a number of different types of resets, including power reset, upon read or apparent loss of power for more than a second and linc reset for clearing circuits but not changing error count registers in the system. An implementation of SCI for a switching network which does not contain full agent switches (i.e., switches that have queues), as contemplated by SCI is disclosed which extends the utilization of the above-noted key elements. This implementation provides for a substantial reduction in the complexity, size, power and costs of the network. The network may be expandable in that it can service more than the current number of required operational rings which have at least one scrubber node and may have one or more other functional nodes therein, while handling misrouted packets by providing recirculation conductive connections to all input and output ports of the network that are not connected to such operational rings.
