3 SCI Standard - Dolphin SCI Technology
WHAT IS SCI? The SCI standard ANSI/IEEE defines a point-to-point interface and a set of packet protocols. The protocols use small packet sizes with a 16-byte header and data sizes of 16, 64, 128 and 256 bytes. Packets are protected by a 16-bit CRC code. An SCI interface 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. Bus like protocol with Packet-based handshake protocols and guaranteed data delivery. 64 bits addressing and the most significant 16 bits are used for addressing up to 64K nodes. A set of cache coherence protocols are defined to maintain cache coherence in a shared memory system. Message passing is supported by a compatible subset of the SCI protocols. This protocol subset does not invoke SCI cache coherency protocols.
