CEVA-SATA IP Drives State-of-the-Art Storage Systems

CEVA-SATA_small As a leading provider of Serial ATA (SATA) IP since 2003, CEVA has a strong track record in licensing and supporting this specialist technology.

CEVA-SATA Device Controller IP

CEVA SATA solution

CEVA’s extensive experience with SSD licensees has resulted in a SATA Device Controller IP solution that is tailored for high throughput performance. The optimized Device Command Layer provides hardware off-load for the embedded processor and offers advanced semaphore options for interfacing with system DMA and Cache memory.

The CEVA-SATA Device Controller IP supports the latest SATA3.0 specification for 6Gbps operation. In order to meet the needs of Self Encrypting Drives (SEDs), CEVA has integrated?CEVAnet Partner?AES technology with the CEVA-SATA Device Controller IP to minimize latency and maximize throughput.

CEVA-SATA Host Controller IP

CEVA-SATA AHCI Host Controller and CEVA-SATA Enterprise Host Controller IP packages are available, both supporting SATA3.0 (6Gbps). The AHCI variant is suitable for those applications requiring conformance with standard AHCI software drivers. The Enterprise variant is aimed at embedded applications where the licensee has full control of the software drivers, thereby allowing system customization. In both cases, a feature-rich solution is offered, including hardware assisted FIS-based switching for highest performance in Port Multiplier based systems.

CEVA-SATA IP Target Applications

Target applications for CEVA-SATA Device Controller IP include SSDs and Blu-Ray and other optical storage devices.

Target applications for CEVA-SATA Host Controller IP include Set-Top-Box (STB) and Digital Video Recorders, Media Gateway Servers, netbook and tablet computers, RAID Controllers, and Surveillance Controllers.
