Scalable Coherent Interface
Jump to user comments
hardware, protocol (SCI) The ANSI/IEEE 1596-1992
standard that defines a point-to-point interface and a set
of packet protocols. The SCI protocols use packets with a
16-byte header and 16, 64, or 256 data bytes. Each packet
is protected by a 16-bit CRC code.
The standard defines 1 Gbit/second serial fiber-optic
links and 1 Gbyte/second parallel copper links. SCI has two
unidirectional links that operate concurrently.
The SCI protocols support shared memory by encapsulating
bus requests and responses into SCI request and response
packets. Packet-based handshake protocols guarantee
reliable data delivery. A set of cache coherence protocols
are defined to maintain cache coherence in a shared memorysystem.
