SIP platform and DSP core licensor Ceva Inc. recently launched its 12Gbit/s Serial Attached SCSI (SAS-3) Controller IP for licensing. Ceva's latest IP enables customers to design best-in-class next generation enterprise storage products in a timely and cost-effective manner.

SAS-3 is the third generation of the Serial Attached SCSI interface, a serial storage interconnect which is widely favoured in enterprise applications. Driven by the increasing performance capability of storage devices which are already saturating the 6Gbit/s line rate of SAS-2, designers are eager to adopt 12Gbit/s SAS-3.

Ceva's SAS Controller IP provides a comprehensive solution with advanced features including SCSI SBC-2 End-to-End Protection (DIF), powerful full duplex DMA supporting Scatter/Gather operation with a flexible AMBA AXI interface, narrow and wide port support plus multiple optimisations for maximising IOPS in both Initiator and Target (SSD) applications. The IP contains a Phy Control Layer which implements the state machines required for SNW4 and 12Gbit/s link training sequences. This flexible interface layer simplifies integration with 3rd party or customer's SAS Phy. In addition to ASIC/ASSP silicon deployment, the IP is also suitable for implementation in leading Xilinx / Altera FPGAs, employing the Phy embedded therein.
