Synopsys unveiled the DesignWare SATA AHCI host and device digital controller IP for the latest SATA 6 Gigabit per second (Gbps) data transfer rate as defined in the Serial ATA (SATA) Revision 3.0 specification. This doubles the data rate of the previous (version 2.6) specification. DesignWare SATA IP speeds the deployment of the 6Gbps interface into solid state drives and enterprise class storage system SoCs. The DesignWare SATA AHCI host and device digital controllers and verification IP for SATA 6Gbps are available now.
The DesignWare SATA digital controllers for the SATA 6Gbps data transfer rate support numerous features available in the SATA Revision 3.0 Specification — including new streaming Native Command Queuing (NCQ) and power management states. Streaming NCQ introduces isochrononous priority to help improve the quality of service for audio/video streaming.
For more power efficient systems, the DesignWare SATA controllers implement power mode states that allow a direct transition from partial to full slumber mode, bypassing the active state. In addition, the well-defined embedded DMA engine enables designers to achieve optimal system performance while maintaining low latency and minimal CPU overhead. The included VMM-enabled DesignWare SATA Verification IP speeds the development of powerful SystemVerilog testbenches.
Synopsys provides designers with a complete DesignWare SATA IP solution consisting of the device and host digital controllers, PHY and verification IP, which are silicon-proven and shipping in volume production. The complete solution has passed the latest SATA-IO Building Block interoperability testing at the SATA 3Gbps data transfer rate. Synopsys will participate in the SATA 6Gbps interoperability testing as it becomes available.
