The Challenge: Complete SATA Storage Without CPU Software Overhead
SATA SSD is still a practical choice for long-lifecycle FPGA systems that require
proven connectivity, lower power, relaxed PCB routing, and broad SSD availability. However, a raw SATA
link is not enough to build a complete storage application. The design must also implement the
host-controller layer that manages SATA device access before higher-level functions such as RAID0
striping or a file system can be added.
Design Gateway solves this with a layered hardware architecture. SATA-IP handles the SATA protocol and
high-speed serial interface. HCTL-IP adds the host-controller layer and command control. On top of
SATA-HCTL, Design Gateway provides ready-made top-up modules for RAID0 and exFAT, allowing customers
to scale performance, increase capacity, or write standard exFAT files while keeping the data path in
FPGA hardware.
