NVM Express

Mobiveil’s NVM Express Controller is highly flexible and configurable design targeted for both Enterprise and client class solutions that unlock the current and future potential of PCIe-based SSDs. The core efficiently supports multi-core architectures ensuring thread(s) may run on each core with their own queue and interrupt without any locks required. The controller architecture is carefully tailored to optimize link and throughput utilization, latency, reliability, power consumption, and silicon footprint. Mobiveil’s NVM Express controller can be used along with its PCI Express controller (GPEX) and any third party NAND Flash controller.
