Description

SD Express FPGA IP core enables high-speed data transfer by leveraging PCIe and NVMe protocols over an SD card interface. It supports backward compatibility with legacy SD modes while offering significantly enhanced performance for storage applications. This enables the high-speed data transfer for next-generation storage applications as it supports the data rates significantly higher than traditional SD cards. Designed for FPGA-based implementations, it provides flexibility for custom storage solutions in embedded and industrial applications.
