Serial storage architecture

Ian David Judd; Philip J. Murfet; Michael J. Palmer

This paper describes Serial Storage Architecture (SSA), a definition and general specification of a high-performance serial link for the attachment of input/output devices. An overview is given of the architecture itself, followed by a general description of the hardware implementation of a dual-port SSA node on a single chip.
