Ceva has launched its 12Gbps Serial Attached SCSI (SAS-3) Controller IP for licens ('licence' when noun)ing. The company's SAS-3 IP aims to enable designs for the next generation enterprise storage products.

SAS-3 is the third generation of the Serial Attached SCSI interface, a robust, high performance serial storage interconnect which is widely favoured in Enterprise applications. The 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.

"Our latest SAS-3 IP affirms our commitment and unique expertise in the SAS controller space," said Aviv Malinovitch, Ceva's vice president of communications. "Our previous generations of SATA/SAS technology achieved significant market success, deployed in millions of devices to date. Our SAS-3 IP builds on this success and early customer engagements with leading industry players have provided excellent feedback, both in relation to the comprehensive feature set of our IP and the expert support that we provide," added Malinovitch.

The IP also contains a Phy Control Layer which implements the state machines required for SNW4 and 12Gbps link training sequences. This flexible interface layer simplifies integration with 3rd party or customer's SAS Phy. Further, Ceva can provide an integrated solution with a number of leading Phy IP partners. In addition to ASIC/ASSP silicon deployment, the IP is also suitable for implementation in leading Xilinx / Altera FPGAs, employing the Phy embedded therein.
