ZYNQ SATA 3 AHCI Host Controller with Linux Driver
Overview
The LDS SATA 3 HOST AHCI XZ7 IP incorporates the AHCI registers model, the Transport layer, the Link layer and the PHY layer on a Xilinx Zynq speed grade 2 FPGA. The LDS_SATA 3 HOST AHCI XZ7 IP is compliant with Serial ATA III specification and signaling rate is 6Gbs. The LDS SATA 3 HOST AHCI XZ7 IP is fully synchronous with system frequency (Clock_sys) at 75MHz in case of 3Gbs speed selection and 150MHz in case of 6Gbs speed selection. The source code format is available for ease of customization. The customization can be done by Logic Design Solutions.
