systems with "no-CPU" budgets and light wattage footprints can go to

|Editor:- April 19, 2017 - A dilemma for designers
of embedded systems which require high SSD performance is how can you get
the benefits of enterprise class NVMe SSDs for simple applications - which
integrate video for example - without at the same time escalating the wattage
footprint of the entire attached micro server?|
A new paper published
today by IP-Maker
server-class storage in embedded applications (pdf) discusses the problem
and how their new FPGA based IP enables any NVMe PCIe SSD to be used in
embedded systems to provide sub-microsecond latency using "20x better power
efficiency, and 20x lower cost compared to a CPU-based system."
company says the NVMe host IP - which is now available - can be used in an FPGA
connected between the PCIe root port and the cache memory, internal SRAM or
external DRAM. It fully controls the NVMe protocol by setting and managing the
NVMe commands. No CPU is required. It supports PCIe gen 3 x 8 interface.
Michael Guyard, Marketing
Director said that - among other things - applications include:-
- military recorders
- portable medical imaging
- mobile vision products - in robots and drones
Editor's comments:- Now Cinderella
embedded systems with low cost budgets and low wattage footprints can go to the
enterprise NVMe performance ball. The new magic - in the form of the FPGA IP
released today by IP Maker - has the potential to transform the demographics
and class of SSDs seen in future industrial systems.
|There are several
variations possible in the future implementation of NVDIMMs which aim to
replace DRAM with tiered DDR-4 flash. |
Design approaches which
leverage the motherboard DRAM in other sockets on the same motherboard -
such as Memory1 from Diablo - have more flexibility in their flash to DRAM ratio
than "all in one" designs which place all the memory and the
controller in the same single package.
The latter approach carries
the same market risks as the old
drives in the notebook market.
They are optimum ratios for only
a very limited set of applications and configurations.
