产品描述
NVMe (Non-Volatile Memory Express) has become the prominent choice for connecting Solid-State Drives (SSD) when storage read/write bandwidth is key. Electrically, the NVMe protocol operates on top of PCIe; it leaves behind legacy protocols such as AHCI, and thus scales well for performance.
MLE has been integrating PCIe, and NVMe, into FPGA-based systems for a while. Now, MLE releases NVMe Streamer which is a so-called Full Accelerator NVMe host subsystem integrated into FPGAs, and most prominently into AMD Zynq Ultrascale+ MPSoC and RFSoC devices.
MLE's new NVMe Streamer is the result of many successful customer projects and responds to the embedded market's needs to make use of modern SSDs. NVMe Streamer is a fully integrated and pre-validated subsystem stack operating the NVMe protocol fully in Programmable Logic (PL) with no software running, keeping the Processing System (PS) out of this performance path. For AMD FPGAs, NVMe Streamer utilizes AMD GTH and GTY Multi-Gigabit Transceivers together with AMD PCIe Hard IP Cores for physical PCIe connectivity.
