rmNVMe-IP, Random Access plus Multi User NVMe Host
Combine random I/O optimization with concurrent multi user access in a single hardware NVMe host that does not require a CPU or external DDR.
rmNVMe-IP is built for systems that need both high random IOPS and multiple data streams at the same time. The core schedules commands and moves data in pure logic, which delivers predictable latency under mixed workloads while keeping interfaces simple for RTL integration. It suits event capture with live analytics, shared scratch storage at the edge, and pipelines that interleave frequent small updates with larger transfers.
Highlights
- Hardware NVMe host optimized for random I/O with multi user concurrency
- No CPU and no external DDR required
- Configurable buffering to tune for read heavy, write heavy, or mixed access patterns
- Simple FIFO or AXI-style user interfaces for control and data
- Compact resource usage compared to CPU based stacks
- Reference designs available to shorten bring up
