Overview

The NVMe controller core (Meissa) is compliant with NVM Express 1.4 specification (NVMe 2.0 Mandatory) and targeted for both enterprise and client SSD markets. It is a highly hardware automated design that requires minimum SW/FW involvement from the CPU. It supports out of order IO read data transfer and can boost the IOPS performance and minimize the latency of SSD controllers. The end-to-end data protection and the error handling mechanism of Meissa enable the robust and reliable SSD controller designs. Meissa is designed with scalability in mind and can easily support throughput up to 32GB/s. Meissa is also highly flexible and can be configured to fit in the requirements of different applications. Meissa is delivered with a complete development package for the ease of use in both FPGA and SoC design.

NVMe powers SSDs in the enterprise

With the emergence of non-volatile memory express (NVMe), a scalable host controller interface specifically developed for PCIe SSDs, and a supporting ecosystem plus dedicated devices such as NVMe programmable flash controller chips, the potential of PCIe SSDs for enterprise computing applications can be fully realized.

Controller Memory Buffer (CMB): NVMe 2.0’s On-Controller Memory Feature

Non-volatile Memory Express (NVMe) has become the dominant interface protocol for high-performance storage devices. As workloads demand ever-lower latencies, the NVMe specification has evolved with features that reduce data-path overhead. One such feature is the Controller Memory Buffer (CMB), which exposes on-controller memory directly to the host system.

NVMe host IP for computing accelerator

NVM Express (NVMe) SSDs are well adopted by the storage industry. It delivers high performances in term of IOPS, throughput and latency. It comes with a various range of capacity and form factors including PCIe Add-In-Card, 2.5" U.2, M.2 and recently as a single BGA chip.
