Cadences NVMe sub system is 1.0 rev C compliant and the first in the industry to offer a hardware end to end solution from PHY to SoC fabric. To complete the sub system a software stack that enables setup and initialization and command processing is also included to form a complete sub system solution. This offers many advantages to the SoC design team by offering a complete verified sub system block that terminates at a known point for HW as well as a defined API interface for system software. The bus interconnects between PHY, PCIe controller and NVMe are already optimized and require no additional logic.
The number of I/O Queues supported can be configured up to the maximum of 65536 Queues.
Support PCIe features such Bifurcation, SRVIO, MIMO and others
Support for Weighted Round Robin with Urgent Arbitration Mechanism
PCIe is Fully configurable FIFOs and RAMs along with several configuration options such as ECC, end-to-end datapath parity, ECRC support
Admin Queue commands to create or delete I/O Queues are handled autonomously without local firmware support
Support for up to 256 functions (physical (PF) or virtual (VF)) with ARI support
Support for X1 up to X16 lane configurations with X16 configuration performing dual-packet processing per cycle for maximum throughput
Software abstracts all NVMe controller functionality for a local CPU with minimal application assistance, and performs sub system initialization and all commands that are not hardware accelerated.
Readable and commented RTL, fully regressed by Cadence for each delivery
Synthesis Scripts and STA script
Basic Test Bench
Firmware stack in C source code
