Overview
The DesignWare IP for Serial ATA (SATA) Device Controller is compliant to the SATA 2.6 specification for 1.5 and 3 Gb/sec and the draft SATA 3.0 specification for 6Gb/sec operation ensuring scalability and reuse in current and future SoCs. The digital device controller offers an integrated DMA with a well defined, flexible programming model that minimizes software overhead ensuring maximum operational performance. Sample device firmware for various applications is available on request.

The core configuration offers one-click integration with the DesignWare SATA PHY IP removing the effort of integrating the digital and mixed signal portions of the SATA interface design. Reduced gate count and very low power consumption is achieved by utilizing the set of highly configurable options which enable the core to be optimized based on the exact design requirements. The test environment for the digital device controller IP includes a number of the DesignWare Verification IP components offering SATA transactions generation, SATA protocol monitoring and AMBA subsystem transaction generation. Verilog-based tests are provided as examples to accelerate system integration.
