CPU-less SATA Host IP core is an all-in-one solution integrating the application, transport, and link layers, enabling direct connection to the PHY layer without CPU or DDR usage. The SATA PHY, implemented in HDL to control the transceiver according to the SATA protocol, acts as the interface between the SATA HCTL IP and the SATA device. This PHY design is included in the reference design provided to IP customers.
