Ceva and Gennum’s Snowbush IP Group have entered into a partnership to deliver a Serial Attached SCSI (SAS) 2.0 IP offering optimised for embedded storage applications. The integrated offering combines Snowbush 6.0Gbps PHY IP integrated with Ceva’s SAS 2.0 Controller IP.
Aviv Malinovitch, vice president of operations at Ceva, said: In particular, the rich feature suite and flexibility of our complete SAS offering is ideal for deployment in embedded SSD controllers, removing the need for discrete bridge chips and thereby increasing performance and reducing overall cost for SAS-enabled SSD designs.
The CEVA-SAS 2.0 controller IP provides both target and initiator functionality and supports features including SCSI SBC-2 end-to-end protection (DIF) and full duplex DMA with IEEE 1212.1 Scatter/Gather. It provides a configuration, control and alarm / status monitoring interface with metric counters and error injection facilities. With programmable control for vendor specific features, the Ceva-SAS 2.0 controller IP enables customers to create differentiated SAS 2.0 products.
The Snowbush-SAS PHY IP is designed for integration into SoC designs for storage applications in process geometries ranging from 130nm down to 40nm. The Snowbush-SAS PHY’s programmable transmit driver can produce 1.8V p-p output swings, exceeding the SAS-2 specification requirements for maximum peak-to-peak voltage.
Ewald Liess, general manager of the Snowbush IP Group for Gennum, said: Since the inception of the SATA and SAS standards, both CEVA and Snowbush have been industry leaders in serial storage IP, offering customers the best solutions available. Snowbush is excited to partner with CEVA to deliver a leading-edge SAS 2.0 solution.
By integrating best-of-breed technologies from both companies, we can offer a complete PHY plus Controller SAS 2.0 IP solution to our customers, further shortening the time to market for SAS 2.0 products.
