| Scalable Coherent Interface (SCI) The / 1596-1992 that defines a point-to-point and a set of . The SCI protocols use packets with a 16-byte and 16, 64, or 256 data bytes. Each packet is protected by a 16-bit code. The standard defines 1 Gbit/second links and 1 Gbyte/second copper links. SCI has two unidirectional links that operate concurrently. The SCI protocols support by encapsulating requests and responses into SCI request and response packets. Packet-based protocols guarantee reliable data delivery. A set of protocols are defined to maintain cache coherence in a . is supported by a compatible subset of the SCI protocols. This protocol subset does not invoke SCI cache coherency protocols. SCI uses 64-bit and the most significant 16 bits are used for addressing up to 64K . {http://www.uni-paderborn.de/pc2/systems/sci/}. [Applications?] (1999-03-22) |
