CEVA Inc. has begun the licensing of its 12Gb/s Serial Attached SCSI (SAS-3) Controller IP that the company said can enable 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 interface, a robust, high performance serial storage interconnect that is widely favoured in enterprise applications. Driven by the increasing performance capability of storage devices that are saturating the 6Gb/s line rate of SAS-2, designers are eager to adopt 12Gb/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 that 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, stated the company. Also, CEVA can provide an integrated solution with a number of PHY IP partners. In addition to ASIC/ASSP silicon deployment, the IP is also geared for implementation in Xilinx/Altera FPGAs, employing the PHY embedded therein.
